Tile problem: Working on 1.3 and not on 1.3.1

Question

Ok, I've already sent this as a bug in JavaFX Jira but it's not public yet, so I'm going to post it here in case someone can understand what is really happening. The problem timeline is the following:
- I have a tile with 3 rectangles that had a roll over effect (they scale their size)
- After 1 second I remove all of the rectangles, so the tile has 0 elements and the rectangles are not shown.
- One second later a put again 3 rectangles in the tile and at this point we have to different behaviours:
- In 1.3 the three rectangles apear without problems
- In 1.3.1 none of them is shown, but strangely if I put the mouse over their "virtual" position the rollover is done and all of them
magically appear (not only the one I was over)

Answer 1

There is no need to override create function anymore in 1.3 and in fact the children variable was created to avoid memory consumption because many CustomNodes create a Group in 1.2. Anyway I changed my code to override create() and as I supposed the result was the same. This code was working also with JavaFX 1.2 without any problems (overriding create() of course)
