It's hard to tell from the code. The "not relevant here" code looks very
suspicious though.
Did you try just stepping over this in the debugger with the simulator?
I assume you reproduced it there so just step over the lines and see what's
going on. Are the components physically added but not visible?
Are they added to the wrong location or not sized correctly?
