Transitions in Easy Wizard are weighted, or ranked. Weight allows to set an order of transitions.

Here comes another feature of Easy Wizard: its states refer to domain data (or directly store the needed data). <b>Each state refers only to the data that it can modify</b>. Thus, it is very easy to update data which is relevant to current state of FSM.</p> <p>What if domain model cannot be updated? The answer is simple: <b>Easy Wizard does not move from the current state, until at least one valid outgoing transition is availaible</b>. Transitions can validate any conditions they need, and most often they check the validity of input data and the validity of domain model. So, if domain model cannot be updated, then flow engine cannot move forward either. This is how flow engine is synchronized with domain model.</p> <!-- Last updated: Sat, Mar 26 2005 --> </body> </html> |

DialogAction allows to * create robust user inteface and provides simple event-based programming accounts.</p> * * <p>DialogAction incorporates several innovative design decisions not previously * used in Struts. Some of them are already implemented in other frameworks, * like Ruby on Rails or JSF. Other features are unique to DialogAction.</p> * * <p><strong>Input/Output Separation</strong></p> * * <p>The cornerstone concept of DialogAction is <i>separation of input and output * processes</i>. It solves several issues, related to HTML form input, * like double submit problem, annoying POSTDATA messages, bad usability * when Reload, Back and Forward buttons are used.</p> * * <p>DialogAction defines three different modes of operation:</p> * <ul> * <li><i>action initialization</i> prepares action for use with new set of data; * <li><i>user input process</i> accepts input data, updates domain accounts, * generates error messages; * <li><i>view rendering process</i> generates a result page. * </ul> * * <p>HTTP specification recommends to use POST request method for server state * modification, and GET method for requests with no side effects. Therefore, * input and output processes in DialogAction are cleanly separated * by request method:</p> * <ul> * <li>Browser sends input data to <nop>DialogAction using POST request. * <li>Web application redirects browser to the location of result page. * <li>Browser loads result page using GET request. * Because this pattern includes redirection, it can also be called as * "Redirect-After-Post" or "Post/Redirect/Get". * </ul> * * <img border="0" align="center" src="doc-files/inputaction.gif" width="500" height="540"> * * <p>It must be understood, that redirection is an inherent part of this pattern. * Redirection allows to split one solid "POST input data, respond * with result page" process into two processes, which are completely * independent from server standpoint.</p> * * <p>Separation of input and output improves usability and user experience:</p> * <ul> * <li>Any page can be reloaded without resending input information to the server. * <li>As a consequence, an application does not have to cope with double submits. * <li>Another consequence is that a user does not see "Do you want to resend * POSTDATA?" message. * <li>Using Back and Forward buttons is safe, because only result pages * are browsed. * <li>If an action has several views corresponding to different application * states, every view is displayed in response to exactly the same * GET request. From browser's point of view the action always returns * the same page. This simple trick allows creating <i>web controls</i>. * Even better, some popular browsers like Internet Explorer or * Mozilla/Firefox do not add every result page to browser session history * if pages originate from the same location. * </ul> * * <p><strong>Event Handlers and View Renderer</strong></p> * * <p>Event handlers have the same signature, as execute method, and * process POST events, usually from submit buttons of HTML form. * An initialization event is one exception from this rule, and can be * processed as either POST or GET request. Initialization event has * a default key, DIALOG-EVENT-INIT.</p> * * <p>After input event is processed, DialogAction redirects to itself and * receives GET request from a browser. The same GET request is sent by * the browser when a user reloads a page. In both cases, GET request * is processed by <code>getView</code> method, which renders an output page.</p> * * <p>"Rendering" is probably a too strong word to what <code>getView</code> * method actually does. It simply chooses a mapping name of a JSP page * corresponding to current dialog state, and returns this mapping to Struts * in the same fashion as a regular action.</p> * * <p>If a dialog action has only one page to render, then default * <code>getView</code> implementation, which returns DIALOG-EVENT-VIEW key, * is sufficient. The only thing you need to do is to define * a <code>forward</code> element in the struts-config.xml file, * which maps view key to a JSP page. * * <p>If a dialog action can render different pages depending on application * state, it is called a <i>web control</i>. In this case <code>getView</code> * method should be overriden, and a proper mapping should be returned.</p> * * <p><strong>Default keys and mappings</strong></p> * * <p>DialogAction uses several predefined keys and mappings, to correlate * HTML buttons to handler methods, and to select result pages. These mappings * are defined in DialogConstants class:</p> * * <p>String DIALOG-VIEW-KEY = "DIALOG-VIEW";<br> * This is a default view mapping, mandatory if a dialog action has only * one page to render. If dialog can render different pages depending * on application state, use action-specific mappings. * * <p>String DIALOG-RELOAD-KEY = "DIALOG-RELOAD";<br> * This is a default reload mapping, optional. Can be omitted if * a dialog action redirects to itself for view processing, which is * a default behavior. It is possible to split input and output * processing between two separate actions, in this case use this mapping * to set the "view action" name.</p> * * <p>String DIALOG-EVENT-KEY = "DIALOG-EVENT";<br> * This is a default prefix for dialog events.</p> * * <p>String DIALOG-EVENT-INIT = "DIALOG-EVENT-INIT";<br> * This is a default name of initialization parameter.</p> * * <p><strong>Usage</strong></p> * * <p>DialogAction is supposed to be used for HTML forms, which are submitted * using POST request method. When the form is submitted, DialogAction * dispatches submit event to a handler method. For this to happed, * automatic validation must be turned off. The hander should validate * input data explicitly, and perform accounts update.</p> * * <p>In case of error, the handler should save errors in the session * and redirect to the same action, this is called <i>action reloading</i>. * Would not this cause infinite loop? No, because request for data submission * has POST type, while redirected request for action reloading has GET type. * DialogAction processes requests differently, depending on their type. * Action reloading can be performed automatically, see the example.</p> * * <p>If no errors detected, control is usually handed over to another action. * Redirection is a preferred way to hand over the control to prevent double * submit issues.</p> * * <p>When a user refreshes a page, action treats the request in the same way * as for action reloading, and displays an appropriate view with current * form bean values. This implies that application state must be stored * on server with session or higher scope.</p> * * <p>A special initializing request parameter must be used to initialize * and reset <nop>DialogAction. This is necessary, because there is * no other way to distinguish linking to DialogAction from other page, * explicit refreshing of page corresponding to an action, or action reloading. * Action data will not be cleared by simply navigating to DialogAction, * instead current values will be shown.</p> * * <p><strong>Notes</strong></p> * <ul> * <li>DialogAction extends SelectAction, refer to SelectAction API * for description on how to define handler methods, and how * to name buttons on HTML page. * <li>Make sure that you turned "validate" property off in your * action mapping in struts-config.xml file. Errors must be processed * explicitly in the action class, but you can use any action form you like, * as well as standard <code>validate</code> method of action form. * <li>Make sure that your action form uses session scope to retain form * values between requests. If you are strongly against storing * application state on the server, this action class is not for you. * </ul> * * @see net.jspcontrols.dialogs.actions.SelectAction * @see net.jspcontrols.dialogs.actions.DialogConstants * @version 1.2 * * @author Michael Jouravlev */ public abstract class DialogAction extends SelectAction { /** * Returns the initialization key, or initialization key prefix if * several init keys are possible.

Also, it is possible to change button caption without * rebuilding the application.</p> * * <p>The subclass must define a map, which correlates submit button names * with method names, and handler methods themselves. Each method must have * the same signature as <code>execute</code> method. Subclass should not * redefine <code>execute</code> method.</p> * * <img border="0" align="center" src="doc-files/selectaction.gif" width="485" height="540"> * * <p>Using <code>name</code> attribute has a flip side: * during reset/populate/validate process, Struts assigns request values * to corresponding properties of a form bean. Thus, button keys must be named * differently from other request attributes. Also, the dispatch action * must recognize situation when no submit buttons were activated.</p> * * <p>Therefore, all submit buttons use a prefix in their name. * The prefix is specified by <code>parameter</code> property * of the <nop>ActionMapping. Make sure that you do not use periods * in the prefix and in actual button names, or Struts will try to search * and set the nested property and most likely will throw exception.</p> * * <p><strong>Example of Usage</strong></p> * * <p>The action should be configured in <code>struts‑config.xml</code> * file like this:</p> * <pre> * <action path="/test" * type="org.example.MyAction" * scope="request" * parameter="<b>myapp-submit</b>"/> * </pre> * <p>where: * <ul> * <li><code>org.example.MyAction</code> extends <code>SelectAction</code>; * <li><code>parameter</code> contains prefix of your choice for all * submit buttons on an HTML form. * </ul> * </p> * <p> * The names of submit elements should start from the aforementioned prefix, * for example: * </p> * <pre> * <form action="http://myhost/myapp/test.do" method="post"> * <input type="submit" name="<b>myapp-submit</b>-button-add" value="Add button"/> * <input type="submit" name="<b>myapp-submit</b>-button-delete" value="Fancy Delete button"/> * </form> * </pre> * <p>The subclass of <nop>SelectAction class must implement * <code>getKeyMethodMap</code> method, which defines mapping from button names * to method handlers, like this:</p> * <pre> * protected Map getKeyMethodMap() { * Map map = new HashMap(); * map.put("myapp-submit-button-add", "add"); * map.put("myapp-submit-button-delete", "delete"); * return map; * } * </pre> * <p>The subclass also must implement the methods themselves. For example:</p> * <pre> * public ActionForward add(ActionMapping mapping, * ActionForm form, * HttpServletRequest request, * HttpServletResponse response) * throws IOException, ServletException { * // do add * return mapping.findForward("success"); * } * * public ActionForward delete(ActionMapping mapping, * ActionForm form, * HttpServletRequest request, * HttpServletResponse response) * throws IOException, ServletException { * // do delete * return mapping.findForward("success"); * }</pre> * <p> * <strong>Notes</strong> * <ul> * <li>Subclass should not redefine <code>execute</code> method. * <li>If duplicate values exist for the keys returned by * <code>getKeyMethodMap</code>, the first one will be returned. * If no corresponding key is found then an exception will be thrown. * <li>Cancel button must be handled by implementing standard * <code>cancelled</code> method. * <li>According to HTML specification, at most one submit element is sent * from browser to the server when form is submitted. If form is submitted * without explicitly clicking a button, the result depends on a browser. * Either no buttons are submitted, or the first button defined on the form * is submitted.
