Martin Makundi updated WICKET-2872:
-----------------------------------
Attachment: Wicket-Quickstart.zip
TestCase for reproducing bug.
> 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

> Original Estimate: 1h
> Remaining Estimate: 1h

> 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:
> org.apache.wicket.WicketRuntimeException: 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).
