Layout issues

Scott, in my experience this is not how JavaFX works in general. All my layoutChildren methods are only called when I change a property that directly or indirectly affects the layout, such as changing the text of a label or invoking requestLayout().

Your application must be doing something actively for this to happen, I believe.

Perhaps you could remove parts of your UI until you isolate the component causing the problem.

It's like something is always in the list of "dirty" nodes and is forcing a re-layout.   I don't understand this.  I've googled but I can't find a decent tutorial for implementing custom containers or custom layouts.
