I have a combobox.. it contains a list of value.... when any one item selected, the whole list get change.. i have used action listener to perform this operation...
but i have a problem with it... when i change the items in the combo box, again the action listener is triggered..
i want the event to trigger only when user selects an item in the list..
which listener to use.. i tried with itemlistener.. still the problem remain the same..
i have used thread in my program, so that the screen doesnt look hanging.. Is it becoze of the thread?
Thanks in advance.

When u select an item from the combobox u are making the list to change according to item selected. Right?
After u select the item and before you add the changed list of items to the combobox just remove the actionlistener. After updating the comboxbox with new items now again add the actionlistener. This will solve the problem you are having.
It is sorta covered in the JavaRanch Style Guide.
