Subject Button not visible, except that it is...
Date Mon, 21 Aug 2017 14:47:56 GMT
We have a form that underwent some re-writing.  After the changes, a button
starts throwing the below exception.  The button is in a panel that starts
invisible but is made visible later.  In the event that makes it visible we
logged out the button's isVisibleInHierarchy() and it was false at the
beginning of the method, true at the end.  And the button DID render on the
page.

So if wicket thought the button was visible by it's own method, and chose to
render it, why does it later think it's not visible in the very next event? 
We are not overriding any isVisible() methods in the page.  Any ideas?
