IDEA 13 Does not generate SetModel for JComboBox

IDEA 13 Does not generate SetModel for JComboBox.
During JComboBox creation in UI, I've added tooltips text - "Tooltp text" and model:
1
2
3
4

generated result below

wmcombobox = new JComboBox();
wmcombobox.setToolTipText("Tooltp text");

there is now setmodel call in generated source code.
If I switch from source code to Java class - everything work OK.

     Can you help?
     Sincerely yours...
