I have a listbox like this

 <listbox id="results" height='97%' onSelect="runMethod(self);">

In runMethod i have some code like this

results.getModel().getElementAt(lb.getSelectedIndex()));

The problem is we are receiving sometimes the infamous

java.lang.ArrayIndexOutOfBoundsException: -1

I think the problem is here

lb.getSelectedIndex()

My question is.. is possible that Listbox onSelect event is fired even if listbox has no selected index i mean lb.getSelectedIndex() returns -1?

If so what circumstances would do so...

Any help is hugely appeciate best regards from Venezuela...

I think there was a bug fix for this but i cannot remember in which version it was applied. Maybe if you search the issue tracker?

I would suggest to make a quick check with ZK 6.5.4

Hello javiut,

I will recommend something a little different.

Please change your listbox by adding the selectedItem property.

This way you will have the selected item of the listbox, and you will also be able to add your functionality in your java code.

Please try it out, and let me know the results.

Best Regards,

Darksu
