HudComboboxUI does not paint correctly with empty DefaultComboBoxModel

[GoogleCodeExporter]

What steps will reproduce the problem?
1. HudWidgetFactory.createHudComboBox(new DefaultComboBoxModel())

or removing all elements in the model,  
defaultComboboxModel.removeAllElements() 

What is the expected output? What do you see instead?
A JComboBox with no items, instead I see a collapsed box with almost no height.
Clicking the component results in a ArrayIndexOutOfBoundsException.

What version of the product are you using? On what operating system?
macwidgets 0.9.5 - OSX 10.5.8

Please provide any additional information below.

This code produces the problem:

...
content.add(HudWidgetFactory.createHudComboBox(new DefaultComboBoxModel()));
content.add(HudWidgetFactory.createHudComboBox(new 
DefaultComboBoxModel(items)));
...

see attached image.

Changed display value from "" to " " when there is no selected item. Also added 
check for existence of items 
before trying to show popup. You'll find the latest Mac Widgets for Java build

Did the trick.

However, adding new Objects to the model will not be drawn correctly in the 
drop-down list.
The drop-down list does not update its height, resulting in the items getting 
smaller (height).

...
content.add(HudWidgetFactory.createHudComboBox(model);
...

@Action void add() {
   model.addElement("new element");
}
...

see attached image.

Give it another try -- should be fixed now.

I found another issue.

Adding a new object to a empty DefaultComboboxModel without selecting the newly 
added object will result in a ArrayIndexOutOfBoundsException when clicking the 
JCombobox instance.

I attached code that shows how the error occurs.
