If you have an ImageView nested two levels deep inside a TablePane, the image is aligned incorrectly. I've seen cases that vary from no problem to the top coordinate being so large that the image doesn't display at all.
I wrote about this a long time ago (http://apache-pivot-users.399431.n3.nabble.com/ImageView-messes-up-nested-inside-two-TablePanes-td2514398.html) but apparently neglected to file a bug report. At the time, Greg suggested that the layout code was passing the wrong height to the ImageView.
I'll attach a test case.
