You can override isVisible of the component you need to have the
visibility switched, and have e.g.:
public boolean isVisible()
{
Foo foo = (Foo)getModelObject();
return foo.shouldDisplay();
}

Hi,
I'm currently building a form which has some components which are not
shown sometimes in dependency of model data. I'm not sure how to
build things like that because I found no way to do this in the same
way like other model values are bound to the components
(propertymodels and ognl expressions). My first idea was to do this
myself in the containing form, like in onBeginRequest method, but
this didn't worked out very well because the model data can be
changed after this by event handlers. What's the wicket way of doing
things like that?
Regards,
Ralf
