TextEditor Hide is triggered, but how to find from where?

so i have table component, mostly it’s the same class shown in the juce demo.
So now i got one problem, if i trigger the showEditor() function from a Label, it opens very short the editor and after that the closeEditor function is called.
I tryed to figur out why and it seems like the WindowsMessageHelpers triggers a focusLossMessage.
So it looks for me that some of my other Components steels the label the focus, is that correct?
If yes, what is the best way to find out which component is the problem?

Thanks for your help

Found it,
i had some buttons to change some menu points, in the beginning i had some paint problems so in the paint() they got a btn->setFont(true); the true give’s the Object a Focus which is conflicted with the label editor.
