Basically what I want to do is from this markup:
<span wicket:id="foo>TEXT<span wicket:id="star">*<span></span>
I'd like to replace 'TEXT' with some text from my java code, and would
like to set the visibility of the 'star' span from within my code.
Replacing TEXT seems similar to what a Label does, but a Label won't
support the embedded 'star' span. So I tried to mimic Label my
creating my own component (I tried WebMarkupContainer) and mimic the
behavior of Label, but also allow for the embedded component. So I
tried to override the onComponentTagBody() method with one that calls
replaceComponentTagBody() but that didn't work because that removed
the 'star' span.
So what I'd really like to do would be to create my custom component
and somehow tell it to replace the text of its body (ie. the 'TEXT')
but to do so without removing child components.
Make sense?
