Just to set the record straight regarding the synchronization of view and node transforms, I submitted a test case late yesterday demonstrating this bug, and Kelvin submitted it as a bona fide bug. Note that the problem only occurs when you use the view canvas getImagePlateToVworld() transform. The problem does not occur if you use the view platform's getLocalToVworld() transform (it is a node transform the same as any other node's). Also, the problem seems to be independent of Behaviors. The result is the same whether a Behavior is used to monitor mouse events initiating the event chain or a mouse listener does it. (I didn't test it for Interpolators, which is what Kelvin's example was specifically about, but I'd guess that the problem is independent of that too). --jon > Hi Jon, > > Bug 4363761 is submitted for this.
