Let's assume, `JComboBox` is populated with `Rectangle` objects, a custom renderer is set which displays the value of the `bottom` field in the combo box. Your code, if I understand it correctly, will default to _full rectangle_ rather than what's really displayed.

I need to check with custom renderer. 

If I understand correctly, with current fix the `getSelectedItem` method will return the `rectangle` object and then calling `toString` method will return rectangle's dimension instead of the displayed text in JComboBox and that may result incorrectly. Right?
