I am getting an "IllegalArgumentException: Array is empty" when some users submit a form that persists an EO to my database. The behaviour is sporadic and random. Sometimes saving is successful; sometimes it fails. I haven't been able to isolate any differences in operating environments (browser, platform, version) that can avoid or provoke this behaviour consistently so I'm at a total loss to explain it.

The problem turned out to be an unbound form variable. We use JavaScript to simplify some form manipulations. In this case, the JS was saving the value of a select-box item in a field which, on submit, was then mapped by WO to an EO. The problem only showed up if a user didn't select an item in the select box.

Now, in theory, we have code in place to check for this condition, but apparently it's broken. I'm still not sure why this situation resulted in the message "Array is empty", but at least now I know what causes it.
