I think what he's saying is... you press the button "Open window" and then press the button "Change state" and the window closes straight away...
However if you press the "Open window" button and then click to Tab 2 and then Tab 3 and then press the "Change state" button... then the label in each tab changes to a text input field... the bug is it's closes the flex window after you press the "Change state" button without clicking through the tabs ( I had to select 2 different tabs before the "Change state" button worked correctly )
