I was messing around with the combobox tag and found some oddities with it. It didn't seem to support all the attributes that the text field tag did, and moreover, it seems to think it should have a boolean as it's value, when in actuality it should support text, or at least that's how it's velocity template is written. I've enclosed both a rewritten version of the ComboBoxTag class and the simply combobox.vm file that subclasses the textfield and uses the textfield vm. Not really a necessary fix, but I thought I'd mention it to see what you folks thought...
