Re: [Wicket-user] MarkupException using a fragment with a TabbedPanel

Hi All,

I just grabbed Wicket 1.3.0-beta2 and tried to reproduce this problem. The problem still occurs.

I managed to isolate it to a simple use case (see the attachments for Java code and HTML - ZIP attachments get filtered out, so I'm sending the files as is). It looks like it doesn't have anything to do with a TabbedPanel. Instead it looks like fragments do not play nicely with <wicket:message> tags.

Here is the markup for my panel:

<html xmlns:wicket="http://wicket.apache.org"> <body> <wicket:panel> <div wicket:id="test">[test fragment goes here]</div><br /> </wicket:panel> <wicket:fragment wicket:id="testFrag"> <table class="theader" cellspacing="1"> <tr class="bg"> <th><wicket:message key="message.test">[test message]</wicket:message> </th> <td><span wicket:id="label">[test label]</span> </td> </tr> </table> </wicket:fragment> </body> </html>

If I comment out the <wicket:message> tag from my fragment, everything works fine. However when the <wicket:message> tag is in place, a MarkupException occurs and the closing tag </div> is highlighted red (see below).

Do you think this could be a bug in Wicket or is there a problem in my markup/code?

Thanks!

I am migrating my application from 1.2.6 to 1.3.0 and am getting a similar (although slightly different) problem in 1.3.0-incubating-SNAPSHOT.

I'll try to isolate the problem in a small example and follow up.

Hi All,

I am having the following problem trying to use a TabbedPanel inside a fragment. The structure of components is the following: [CompanyDetailsPanel] -> [RelatedInfoFragment] -> [TabbedPanel].

Wicket throws a MarkupException complaining about a missing component ID. The exception message seems to be unrelated to the real cause of the problem. The component IDs in HTML and the panel's Java code match. Below the exception stack trace Wicket displays my markup file and highlights the closing </div> of my fragment.

If I use the TabbedPanel directly from my CompanyDetailsPanel (i.e. without using a fragment), then everything works fine.

I am using Wicket 1.2.6.

Has anybody faced such a problem? Is it a bug in Wicket? Are there any workarounds?

Thanks in advance!
Huergo
