hello all i'm discovering tapestry righ now and it reminds me my delphi days, i love it i was wondering if a web site build with tapestry can be (easily) configured so that it can be used with a browser in a pda or cell phone for example, or (more extreme) by regular plain old voice phone in other words, is it "presentation agnostic"? thanks in advance jaime __________________________________________________ Do you Yahoo!?

I'm glad to see this feature request is still being kicked around. I think it is important regardless of implmentation. I may have jumped the gun when I said "ala jsp." In our case, any solution that would be run efficiently in the normal operating case, but still lets you refresh pages dynamically (using timestamp checking, or "hitting a button" somewhere) would fill the bill nicely. What we don't want is to lose sessions in the process. Joel |

This exists in development as an option, but is expensive (reloads pages every click). This would need to be efficient like JSP. That is, simply check the timestamps on the files to determine whether they are updated. If they are, then reload, w/o flushing any sessions. If the files are in a .zip (ie. .war file), then no updating/checking is necessary. This should be the default. No option necessary, development or production. If you don't need it, .war it. This is highly important and practical for a 24x7 website. Joel ---------------------------------------------------------------------- >Comment By: Howard Lewis Ship (hship) Date: 2003-03-04 12:15 Message: Logged In: YES user_id=26816 Timestamp checking IS possible in theory. I believe that you can get the URL for each resource (even from the classpath, even in a JAR or WAR) and from that, the date last modified. For packaged files, it is the date last modified of the archive. I'm concerned about the performance impact, and the degree to which code will be mangled to support this. Think about this: "check the timestamps". Which timestamps: We're talking about the page template, page specification, and the template and specification of every compoent, recursively. that means that when IREquestCycle gets a page, it has to perform a check on potentially dozens of files (yes, we would gate this, and only perform checks every so often). I would rather spend the effort creating some kind of JMX extension that would link to Tapestry and allow you to safely reset the Tapestry caches, or a smarter version of the reset service that you could invoke from your web browser after uploading new content. These solutions ensure that the running application continues to use the old content until the upload of new content is complete. ---------------------------------------------------------------------- Comment By: Luke Galea (lgalea) Date: 2003-03-04 11:24 Message: Logged In: YES user_id=444918 Could you extend the page service to check the timestamps and have it call the reset service if needed?

Hi, I'm evaluating Tapestry for a project in my current company using Weblogic as the app server (7.0). I don't know why when i do a change in a java file (the Home.java for example) i need to restart the weblogic server in order to see the change. the server is running in development mode. Anyone has a solution for this problem? or maybe i need to use another app server for development. Thanks in advance. Norberto Ortigoza |

What's the appropriate place to validate between two ValidField's? If the user has to enter their email twice, where do I check that they are the same, and how do I tell the ValidField's that they aren't valid? I didn't see an example. Joel |

Hey Folks, While trying to configure a decent development environment ( Eclipse, Tomcat Plugin, Visual SourceSafe Plugin, Tapestry 1.3) with the following requirements: 1) The web application (java , html, page files) is in an existing development tree in an existing project. I don't want to make a seperate project in eclipse ( same classes would be in two projects) 2) I wan't to be able to debug: this requirement leaves me no other opportunity then using the Tomcat Plugin 3) I don't want to restart tomcat on every change I make. For java changes i installed the latest JDK which is able replace code at runtime. For .html and .page files, i tried setting the vm property net.sf.tapestry.disable-caching=true . This had the unwanted side effect of short-circuiting my login mechanism. The login mechanism is implemented like the VLIB. When a user isn't logged in, a PageRedirectException is thrown containing a callback to the actual page. After logging in, the callback is used to return to the actual page. Setting the disable-caching property to true makes this callback null. Anyone any idea how to solve the problem in 3 or any suggestions on how to configure a development environment with the above requirements? All suggestions are welcome. Regards, Lennart |

I was in the same boat. I managed solving this problem by making my first Tapestry page an IExternalPage. In the activateExternalPage(RequestCycle) method I call .getVisit() which seems to appropriately setup the session. I then use RequestCycle..getSession() to grab variables out of the existing session. BTW, Remember to encode the link to the page so that it is stateful.

Thanks Adam. I realized this later. What about multiple references in a page to the same component ? (an inserter for ex). I have a page that makes use of the same inserter component more than once. So I need to define two inserter components int the page specification with different jwcid's that do the exactly the same thing.

Is it possible to make the image a standard IMG tag in the HTML or is some nature of the image dynamic. Not everything has to be done in the .page. if it is static you can simply put it in the HTML. The only time an image would need to be in the .page is if it requires the use of an asset or other dynamic nature. ----- Original Message ----- From: "Elankath, Tarun (Cognizant)" <ET...@bl...> To: "Joel Trunick" <Jo...@Sm...>; <tap...@li...> Sent: Monday, February 24, 2003 8:21 AM Subject: RE: [Tapestry-developer] Image used more than once > Hi Joel, > > Did you manage to find the solution to your problem ?

We built a cross between the Conditional and Any component that created a HTML Tag that only appears when the condition is true that supports informal parameters.

Hi Joel, Did you manage to find the solution to your problem ?

Hi list, I am rather peeved that the conditional component doesn't accept = informal parameters. I have an element with a CLASS attribute that I = wish to display conditionally. Unfortunately, if I give a jwcid to this = element and let it be a conditional component, then the CLASS attribute = is invalid. IMHO, this is a bug. I don't see any good reason as to why informal = parameters are forbidden int the conditional component. As far as good = sense goes, informal parameters should be allowed in all circumstances = for all components, it should only be disabled in case of conflict. I know have to put an un-necessary pair of <span jwcid=3D"ifBlah"> tags = around the element now. This only messes the template, instead of = keeping it inviolate.=20 Regards, Tarun |

Hi tapestry gurus, I have templates that refer to stylesheets and images using relative = paths such as styles/site_common.css and images/logo.jpg. I have these = directories (and their files) present in the WAR file as well. But these don't get included in the resulting page. Do I have to create = an asset for every style-sheet and image used ? That would be extremely = tedious and I don't want to modify the html templates either.=20 All help appreciated, Tarun |

Hi list, I have a dynamic javascript tree that loads nodes on the fly, by obtaining it from the server. (I am using the famous xloadtree script at webfx.eae.net) Nodes of the tree are declared by tree elements (see bottom of email for a xml snippet). The tree content conforms to a DTD. A node which is expandable (ie parent node) must provide a SRC attribute. The SRC attribute must link to an xml file that lists the child nodes for this parent node. Ofcourse this xml file is getting generated dynamically by a single page. This page on the server needs the id of the parent node and generates xml content for its children. My problem is that I need to generate the SRC attribute for a TREE element. In other words I need to get the HREF text which contains both the link to this generating page and a parameter to it (id of the node). I know that I can use the ForEach and the Any component to generate the xml nodes. But how do I put the value of the link into the SRC attribute ? All help gratefully appreciated, Tarun tree> <tree text="Loaded Item 1" action="href://webfx.eae.net" /> <tree text="Loaded Item 2"> <tree text="Loaded Item 2.1" action="javascript:alert(2.1)" /> </tree> <tree text="Load "tree1.xml"" src="tree1.xml" /> </tree> |

Subject: [Tapestry-developer] Failed to acquire page Init
Hi all,
Currently I had successfully constructed a login page and able to =

I had no clue how to solve this and why this error is thrown. Hope =
someone can drop me some hints.
Thanks,

Yes Eric, your explanation did help a bit. Thank you! I have understood what it does, but it still looks a bit like black magic to me. Isn't such a scheme be ad-hoc ? What I understand of rewinding with the illustration that you have given, is that it's basically an operation that enables components to carry out actions using the previous request state, instead of the current one. Am I correct here ? I guess I'll need to experiment with a concrete program example in order to completely get the hang of it.

The basic idea of form rewinding is this: During the regular running of a page, the page is rendered with all of its fields in the form. You fill out the field and submit the form. Upon submission, Tapestry rewinds the page, which means that it takes the values that you filled out in the field and stores those values in their appropriate spot (into the Java Bean Property that you attached to the value binding) and then calls the form listener. During a rewind cycle the page is not rendered into HTML. The analogy is this: You unwind a page when you lay out the forms in HTML, when you submit, you rewind the page and pull back the values in the fields, removing the page from view and replacing it with the next page (which, technically, can be the same page that you just saw). ----- Original Message ----- From: "Elankath, Tarun (Cognizant)" <ET...@bl...> To: <tap...@li...> Sent: Friday, February 21, 2003 3:54 AM Subject: [Tapestry-developer] Can't understand what is form rewinding. > Hi list, > > Sorry for this newbie-style question.
