Subject [jira] Commented: (ACE-41) [webui] Error creating association: java.lang.NullPointerException
Date Sat, 03 Oct 2009 16:03:23 GMT

Angelo van der Sijpt commented on ACE-41:
-----------------------------------------

There are two possible solutions for this issue, either we change the behavior of this button,
or we change the association mechanism to use Drag and drop (code.google.com/p/gwt-dnd ).

> When the user clicks on the   <->  (create association) button (any of them) without
selecting the elements to associate, a popup saying "Error creating association: java.lang.NullPointerException"
is displayed.
> A more "user friendly" message should be displayed instead (or no message at all).
