100% is going to mean that it will try to fit all of its children. Is the panel's height constrained some other way? Maybe put minHeight=0 on the VBox

set the percentageHeight of the VBox to 100% when you load it
You may also need to set the panel verticalScrollPolicy="off".

Thank you for all your help. I actaully figured out how to do so, the fix of setting minHeight=0; does work sometimes and sometime it doesn't its odd, no caching issue but I couldn't wrap my head around it. I found that there is a mesurable() method that is called on Box objects that can be turned off but the easisest of all was to just wrap my VBox in a Canvas object, and it worked just as expected.
Thanks again for all your help,
