I got something working with the example code below (Hello.class is
bookmarkable and mounted). What we would need in Wicket is a
BookmarkableForm class:
StatelessForm form = new StatelessForm("form") {
@Override
protected void onComponentTag(final ComponentTag tag) {
super.onComponentTag(tag);
tag.put("action", urlFor(Hello.class, new
PageParameters()));
}
@Override
protected void onComponentTagBody(final MarkupStream
markupStream,
final ComponentTag openTag) {
super.renderComponentTagBody(markupStream,
openTag);
}
};
I'm not sure that's the best way but I wanted to avoid calling
onComponentTagBody in Form which generates the hidden fields. Ideally, I
should use a WebMarkupContainer but, as you noticed, it adds the changes the
elementname with formname:elementname. Somehow, the Form class manages to
avoid this even though it inherits WebMarkupContainer but I couldn't figure
out. Does anyone now how it does this?
Thanks,
Catalin
