I’ve been working on a nice looking application in JavaFX with some nifty transitions. Doing so, I noticed an odd ‘requirement’ when working with Transitions. The problem arose when I tried to split my interface into different files. On one stage, I used two Stacks that each represented a state. Each Stack was defined in its own JavaFX script and another Script contained the transitions and event handlers.
What happened was that not all Transitions seemed to work. I have not yet been able to determine the root cause of it, but the Transition seemed unable to update properties of its target node. After some frustrated trial and error, I discovered a working solution: put the Transitions in the same file as their target node.
Again, I have not yet found the root cause. If someone can tell me why this is a problem, please let me know. I can’t stand not understanding

If this helps anyone, I have also had problems with complex chains of transitions and the final one not executing “rarely” It seems increasing the delay before the last one helped but not eliminated the problem. I have canSkip false set in the keyframe of the last transition. Javafx 1.3
