Hi Steve,
noticed your msg, I do something similiar in enabling
different behaviors as needed.
Anyway if I am not mistaken given my own application
the problem occurs because the the first click is used
to select (focus) on the canvas / component. My work
around having read your email (thanks) is to have an
additional wakeupOn criteria that is:
new
WakeupOnBehaviorPost(this,MouseEvent.MOUSE_CLICKED)
and whenever you enable the picking behavior also
postID(MouseEvent.MOUSE_CLICKED) to simulate the focus
on the component.
Let me know if this works for you.
Greg.
