NPE at HudComboBoxUI#updateDisplayedItem #51

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

Hey Ken, I'm getting an NPE when trying to apply the HudComboBoxUI to a 
checkbox.  The weird 
thing is that I'm not getting it when running the example DHudControls.

Calling Code:
JComboBox sideCombo = new JComboBox();
sideCombo.setName("side_combo");
sideCombo.setUI(new HudComboBoxUI());
for(Side side: sides) {
    sideCombo.addItem(side.getName());
}

panel.add(sideCombo, "span 2");

Exception:
Exception in thread "main" java.lang.NullPointerException

See patch for fix (simple null check in HudComboBoxUI#updateDisplayedItem)

Let me know if you need more info. -Zack
