how to strip wicket tags for particular component
I'm trying to convert main menu into components to control visibility of
items depending on the user logged in and the context.
I use borders to wrap menu item into <li> tags.
The problem is that the rendered markup contains additional <wicket:border>
and <wicket:body> tags. They breaks the menu and it is eventually displayed
as the simple list.
Stripping wicket tags at the application level would obviously solve the
problem. But I'd like to keep wicket tags for most markup and strip only for
menu.
Can I override Border class somehow and strip wicket tags manually?

For now I use the following workaround
public class CleanBorder extends Border {
private boolean savedStripWicketTags;
public CleanBorder(String id) {
super(id);
setRenderBodyOnly(true);
getBodyContainer().setRenderBodyOnly(true);
}
public CleanBorder(String id, IModel<?> model) {
super(id, model);
setRenderBodyOnly(true);
getBodyContainer().setRenderBodyOnly(true);
}
@Override
protected void onAfterRender() {
super.onAfterRender();
Application.get().getMarkupSettings().setStripWicketTags(savedStripWicketTags);
}
@Override
protected void onBeforeRender() {
savedStripWicketTags =
Application.get().getMarkupSettings().getStripWicketTags();
Application.get().getMarkupSettings().setStripWicketTags(true);
super.onBeforeRender();
}
that looks like a hack. I would prefer a settings on the MarkupContainer
that by default uses the application settings but in case of border can be
overridden.

Turning the 2 lines around might give better results.

What about
@Override
public void onComponentTag( ComponentTag tag){
tag.remove( "wicket:id" );
super.onComponentTag(tag);
}

It is possible to override onRender method. It turned out that it is not
final.
@Override
protected void onRender(MarkupStream markupStream) {
Application.get().getMarkupSettings().setStripWicketTags(true);
try {
super.onRender(markupStream);
} finally {
Application.get().getMarkupSettings().setStripWicketTags(
MyApplication.STRIP_WICKET_TAGS_IN_DEVELOPMENT_MODE);
}
}
But I don't find appropriate method to override to let children render
wicket tags.

it seems that onAfterRender is not the appropriate place to restore settings
... :(

Mathias,
I just posted right after your post :) Anyway thanks.
The problem is that you can not restore origianal settings when the body of
the border is being rendered. At lease it is difficult to figure out what
workaround I could employ.
Thankfully I haven't to care about that in my case so I use it.

This may not be the best solution but it should work
DateTextField dateField = new DateTextField("date", new Model<Date>(new
Date())){
@Override
protected void onBeforeRender() {
Application.get().getMarkupSettings().setStripWicketTags(true);
super.onBeforeRender();
}
@Override
protected void onAfterRender() {
Application.get().getMarkupSettings().setStripWicketTags(false);
super.onAfterRender();
}
};
