RE: tapernate NonUniqueObjectException
Can't you just check in your login listener whether the user already has a valid session? Wouldn't that help? Generally, the problem seems to be, that your code executes before the page-setup involving the merge-back of properties takes place. Do you load your objects in a normal listener? Or in Page.validate()? -Original Message- From: Moritz Gmelin [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 26, 2006 11:43 PM To: users@tapestry.apache.org Subject: tapernate NonUniqueObjectException Hi List Members, I am having troubles setting up an application with tapernate. When the user is logging into my application, a Page ExtPage is injected, initialized, some persistent objects are loaded and the page is returned to the user.

Re: DatePicker error
Hi again DJ, I am just looking at the versions I have. I am using Hibernate 3.1.3. Are you using Java 1.5?

Re: tapernate NonUniqueObjectException
The problem happend when tapernates PersistanceStrategy tried to rollback its state in the injected Page. The page was injected in the form handler of the login form. Injecting the page in the pageBeginRender method of the form page, and cleaning up all persistent objects solved the problem. Thanks. M.

EventListener called several times
Hi all,
I am observing a very strange behavior with EventListener.
On a first example, I have a PropertySelection component that updates an
Insert component under onchange event using @EventListener annotation. Works
fine.
Now I have the same PropertySelection component (A), now updating another
PropertySelection (B) object within the same form (instead of the Insert
component). When A changes, I can see from the dojo console that in addition
to the content of B (which is correctly updated), the javascript code that
registers the onchange event is also executed again (this didn't happen on
the example with the Insert component). As a result, it seems that the event
is registered twice: when A changes again, my listener is called twice, then
four times on the following change, etc
Does that make any sense to you guys?
extracted from the dojo console when component A changes:

Re: EventListener called several times
I was running my application with caching disabled on my dev environment. If
I enable caching, then guess what... it works as expected (events are sent
only once when A changes). Amazing.
After a closer look, it seems that the updated event registration script is
sent with a different id (formEventn) when caching is disabled, thus
not cleaning previously registered events.
I'm really happy to have this sorted, since this looked as a show stopper
for a production application. It is still a bit annoying on dev
environments, but I can live with this (until jesse releases a fix ;-)

Re: Components containing dynamic number of component
Hi Jacob, I don't have any didactic example to explain this well, but you can do this like this: For each component, you create a model, or a object that each component receives and interact with him. So, you create a component that receives a List of Objects, iterating over then, and, depending on the type, call the respective component to render. Use If component around each component and the instanceof to evaluate the condition. So, you use the component that receives the List inside your column component, and pass the List of objects to them... If you can't do, I will try to find some code that you can understand... :) Mael On 9/27/06, jake123 [EMAIL PROTECTED] wrote: Hi Mael, thank you for your answer. Have you done this your self?

With the the For Component, and a little of polymorphism applied to components and its models you can do It easily. I don't think you have to work with AbstractComponent, RenderBody, or that kind of thing... A tip... always try to work with components hierarchy... When you work with Tapestry, think on Tapestry approach... the things almost are simpler than you think... ;) Mael On 9/26/06, jake123 [EMAIL PROTECTED] wrote: Hi, I am pritty new to tapestry and I am working with tapestry 4.0.2.

Re: Custom exception page
Exactly. Then in your *.application file, put something like
page name=Exception specification-path=/ErrorPage.page /
and make sure that page has the API that tapestry's internal exception
page has. To save you the trouble, here's tapestry's exception page class:
public abstract class Exception extends BasePage implements
PageDetachListener {
/** Transient property */
public abstract void setExceptions(ExceptionDescription[] exceptions);
public void setException(Throwable value) {
ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
ExceptionDescription[] exceptions = analyzer.analyze(value);
setExceptions(exceptions);
}
}
I should mention that there are other gurus on this list who can
probably tell you how to make all this stuff log by properly configuring
hivemind. But if you want to play with the message, my code should suit
you.

So in Exception.html I could just have a

Look at tapestry's ExceptionDisplay component source. It uses something
called an ExceptionAnalyzer and also displays the contents of the
ExceptionDescription.getProperties().
I've got a custom exception page that writes to log4j. Here's what I
use to get the text:
public void logException(Throwable value) {
ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
ExceptionDescription[] exceptions = analyzer.analyze(value);
setExceptions(exceptions);
StringBuffer text = new StringBuffer();
for (ExceptionDescription exception : exceptions) {
text.append(Class: + exception.getExceptionClassName() +
\n);
text.append(Message: + exception.getMessage() + \n);
for (ExceptionProperty property : exception.getProperties()) {
text.append(Property: + property.getName() + = +
property.getValue() + \n);
}
}
String[] stack = exceptions[exceptions.length-1].getStackTrace();
for (String stackItem : stack) {
text.append(stackItem + \n);
}
log.error(text.toString());
}

Re: Custom exception page
Here you go, it's pretty easy to change whatever you want if you take a look
at tapestrys core exception page configuration file (which you can of course
override with your own contribution values):
http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-framework/src/descriptor/META-INF/tapestry.error.xml?view=markup
As well as the actual exception pages themselves :
http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-framework/src/java/org/apache/tapestry/pages/

Jetty 6 / Tapestry 4 sample code?
Sorry for the newbie question (the FAQ for this mailing list is empty?) but I've been banging my head on this wall for a bit. I've written some small test Tapestry 4 applications and deployed to Tomcat with no trouble. But what I'd like to do is to completely embed the servlet engine in my code. Jetty seems to be a good tool for that. But I haven't been successful putting together a Jetty 6 servlet with Tapestry. I can't even tell if I'm calling the wrong methods in Jetty, or my configuration is wrong or what. So, are there any trivial examples of code with this stack? All the examples I've seen so far have been with old code and I'd rather start with the most recent releases.

Re: Jetty 6 / Tapestry 4 sample code?
I was able to do this recently without too much trouble by studying this code (though I use HtmlUnit as the client, rather than Selenium): http://svn.apache.org/viewvc/tapestry/tapestry5/tapestry-core/trunk/src/test/java/org/apache/tapestry/integration/IntegrationTests.java?view=markup http://svn.apache.org/viewvc/tapestry/tapestry5/tapestry-core/trunk/src/test/java/org/apache/tapestry/integration/JettyRunner.java?view=markup It assumes a Maven2 directory structure, but you might be able to get some ideas even if you aren't using Maven.

Re: Jetty 6 / Tapestry 4 sample code?
You'll find that all of the demo applications (workbench / timetracker ) in tapestry4 all use iddy bitty little jetty.xml conf files to run them off of as well.

Doubt about assets
