Regarding the first issue. So far we haven't really been focusing on = this kind of exception handling functionality, so I'm not sure it's = going to be in PR4. However, it is certainly a topic that's still on our = TODO list. The second issue (OSIV) is not related to SWF but should be resolved in = the Spring 1.3 timeframe since that's when Portlet support will be = included.

Am I right.. If so will those come in PR4?

Subject: Re: [Springframework-developer] Spring Web Flow PR3 = Released Handling session timeouts? Are you talking about HTTP sessions? If = so, there is nothing in SWF related to this.

If you're talking about FlowSession and FlowExecution expiry, There = is not really anything like that available in SWF for the moment. = However, there is the = org.springframework.web.flow.support.ExpiredFlowCleanupFilter that will = cleanup FlowExecutions that have timed out (expired).

Subject: [Springframework-developer] Spring Web Flow PR3 = Released Dear Spring Community, =20 I'm pleased to announce the release of Spring Web Flow Preview = 3. This is a major new release with a substantial number of new = features: both in terms of power and convenience. This release is = considered stable for development use. =20 To download, access: = http://sourceforge.net/project/showfiles.php?group_id=3D73357&package_id=3D= 148517 =20 Note: there are a few incompatible changes between PR2 and PR3. = For a listing and a porting guide, access the change log here: = http://opensource.atlassian.com/confluence/spring/display/WEBFLOW/Change+= Log =20 Contained within this release are a number of new and noteworthy = enhancements. Here are some of them: =20 View State Enhancements =20 - Each view state may now be configured with one or = more setup actions. This action is executed after the state is entered = but before control is returned to the client for response rendering. = This reduces (and in many cases eliminates) the need for setup action = states, making for more concise flow definitions. =20 - Each view state may now select the view to render and = all supporting model data in a fully dynamic, pluggable fashion using = the new ViewDescriptorCreator strategy. =20 - Powerful redirect expressions are now supported, with = full-support for resolving redirect parameters in a dynamic fashion from = the flow RequestContext. =20 Here is an example of these new features in action: =20 Setup actions =20 <view-state id=3D"displayCriteria" view=3D"criteriaView"> <setup bean=3D"searchFormAction" = method=3D"setupForm"/> <transition on=3D"submit" to=3D"executeQuery"> <action bean=3D"searchFormAction" = method=3D"bindAndValidate"/> </transition> </view-state> =20 Redirect expressions =20 <end-state id=3D"end" = view=3D"redirect:/myFlow.htm?input=3D${flowScope.input}"/> =20 Subflow Attribute Mapping Enhancements =20 - Subflow input and output mapping policies are now = fully configurable via a XML flow definition. =20 - Expressions may also be specified that resolve = subflow input attribute values in a dynamic fashion. =20 For example: =20 <attribute-mapper> <input value=3D"${sourceEvent.parameters.id}" = as=3D"id" type=3D"long"/> </attribute-mapper> =20 The expression language used is also pluggable - by default web = flow will try OGNL, if it's not found on the classpath it'll use = Spring's BeanWrapper. =20 Annotated Definition Objects =20 - In addition to action execution parameters, each core = definition object in the system--Flow, State, and Transition---can now = be annotated with arbitrary property metadata. Such properties are = specifiable in the webflow xml definition using the "property" element, = with full support for from-string type conversion with convenient type = aliasing. =20 For example: =20 <transition on=3D"submit" to=3D"executeQuery"> <property name=3D"submitPressed" value=3D"true" = type=3D"boolean"/> </transition> =20 In this case this 'submitPressed' boolean property would be made = available to this transition's target state after entering for = reasoning. =20 Enhanced Flow Execution Listener Callbacks =20 - Listeners responding to the lifecycle of an executing = flow now have more hooks to insert custom logic-notification now happens = when a flow is starting, started, paused, resumed, entering a new state, = entered a new state, or ended---with veto capability for proposed flow = state changes (to facilitate state precondition checks, for example). =20 --- =20 These are just some of the new features of this release. For a = full list of changes, see = http://opensource.atlassian.com/confluence/spring/display/WEBFLOW/Change+= Log =20 As always, we very much value your feedback. One or two more PR = releases to go and we'll be at 1.0 final! J =20 Cheers, =20 Keith Donald Erwin Vervaet =20 Interface21 - http://www.springframework.com This message is a PRIVATE communication.
