Hi, here is the problem, combobox selection reappears after deleting it:
https://examples1.ext.net/Examples/F...riggerButtons/

1. select any value from drop down
2. mouse click somewhere near Reload (not on Reload)
3. delete combobox text using keyboard (not trigger button)
4. mouse click somewhere near Reload (not on Reload)
5. PROBLEM: trigger is hidden, value is shown.
