A DESCRIPTION OF THE PROBLEM :
To get the text in an editable ComboBox selected when it gets focused, I added a listener to the 'focused'-property of the editor inside the ComboBox.
In this listener the editor's 'selectAll' method is called.
I expected the text to be selected when the ComboBox's editor gets the focus, but this doesn't happened.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the provided code. Enter some text inside the ComboBox and switch the focus between the ComboBox's editor and the Button.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When the editor has the focus the text should be selected
ACTUAL -
The text is not selected when the editor gets the focus.

REPRODUCIBILITY :
This bug can be reproduced always.
