Tried that, it doesn't work, gives
Event 'action' from ObjectEdit:edit.organizations.add received an event
handler method return value of

does not support return values from event handler methods.

In that case, why not just trigger the action yourself?
void onSelected() {
resources.triggerEvent("action",contextArray,null);
}

I am creating a component which behaves like an ActionLink but is
form aware in the sense that the form is submitted and then the
actionlink is called.
It all works fine when I persist the link (building it in the render
phase). But was hoping to not need the persit. Then again, it should
not be too bad as it is using flash persistence.

Indeed. Problem is that I don't need it until the button is
clicked. Then in the onSelected() I build the "Link" to redirect to.
It seems a bit backward (and waste of data in the session) if I
have to build this link during render and persist it until the
button is clicked (if it is).
Any ideas how to fix this?
THanks for the help,

getting a NPE trying to access the page's root element (page is
null).
Page is obtained from the active page from the page render queue.
So, it looks like you're trying to create an action link while no
page is rendering.
Cheers.

Using the latest snapshot of tapestry5.
In the following code :
@Inject
private ComponentResources resources;
/**
* Act upon the "link"
*/
void onSelected()
{
Link link = resources.createActionLink( "action", false,
contextArray );
}
I get a NPE with the following stack trace
