Making an invisible panel visible via AjaxLink
Hi: Gurus I am trying to make an invisible panel visible via Ajax link, but
got stuck at a point where I don't know how to proceed further. Please see
the code snipet below
final RegisteredUserPanel registeredUserPanel = new
RegisteredUserPanel("registrationPanel");
add(registeredUserPanel);
registeredUserPanel.setOutputMarkupId(true);
registeredUserPanel.setVisible(false);
add(new AjaxLink("registerLink") {
@Override
public void onClick(AjaxRequestTarget target) {
registeredUserPanel.setVisible(true);
target.addComponent(registeredUserPanel);
}
});
the problem is that when I call registeredUserPanel.setVisible(false),
becuase by defualt I don't want this pannel to be visible; the wicket don't
render the html markup for the pannel at all and hence the ajax calls fails
becuase it don't find the markup to render the panel. Any suggestions how to
tackle a situation like this.
Regards,
RJ

Maybe setOutputMarkupPlaceholderTag(outputTag) can help you?

setoutputmarkupplaceholdertag that ernesto mentioned is the
"non-trick" solution to your problem.

Re: Making an invisible panel visible via AjaxLink
Posted by Matt Welch <ma...@welchkin.net>.
The key, as others have alluded to and you discovered yourself, is that
setting a component's visibility to false will cause that component to not
be rendered. I know in the back of some people minds (mine included) we
think "invisible means it's there, we just can't see it). Well, in this case
invisible means it's not rendered at all. This is all just semantics until
you try to change that visibility on the client side (i.e. AJAX). Since it's
not there to being with, you can't really do client side modifications of
it.
So, as Michael pointed out, you can instead put what you want to make
invisible inside a container and then use the Ajax functionality to update
that container and not the invisible item itself. The container will be
re-rendered and now that the internal item is set to "visible" it will be
rendered right along with its parent container.

put the panel in an additional container and add this container
WebmarkupContainer div = new WebmarkupContainer("cont");
div.setOutputMarkupId(true);
div.add(registeredUserPanel.setVisible(false));
then in the onclick stuff
registeredUserPanel.setVisible(true);
target.addComponent(div);
that should do the trick
