Wicket:enclosure does not work properly on <wicket:extend> pages
----------------------------------------------------------------
Key: WICKET-2872
URL: https://issues.apache.org/jira/browse/WICKET-2872
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.8
Reporter: Martin Makundi
Attachments: Wicket-Quickstart.zip
I Just upgraded from 1.4-rc7 to 1.4.8 and I found a bug with enclosures:
I used to have:
<wicket:enclosure child="selectedCustomersLabel">
<tr><th align="left"><wicket:container
wicket:id="customerSelectionLabel"/>:</th><td><wicket:container
wicket:id="selectedCustomersLabel"/></td></tr>
</wicket:enclosure>
And in the code I was used to changing the visibility only for
selectedCustomersLabel
This worked fine with 1.4-rc7. Setting selectedCustomersLabel invisible would
hide also customerSelectionLabel.
Now with 1.4.8 I get an exception that customerSelectionLabel does not have
markup.... if I set it invisible it works, but that's a whole lot of work if I
have to change all enclosures to work like this.
Specifically, THE BUG OCCURS WHEN PAGE HAS <wicket:extend> tag. See attached
quickstart.
What's
the benefit of enclosure like that?
is it a bug, am I doing something wrong or is it a feature?
WicketMessage: The component(s) below failed to render. A common
problem is that you have added a component in code but forgot to
reference it in the markup (thus the component will never be
rendered).
1. [Component id = customerSelectionLabel]
Root cause:
