I found out yesterday that the 'typeAhead' and 'multiselect' options of ComboBox are mutually exclusive, which is a big disappointment for me as I expected to achieve such effects as the one you can see on this page "out-of-the-box": http://www.zackgrossbart.com/hackito/gwt-rest-auto/

I wonder why they *have* to be mutually exclusive? Besides, would it be hard to implement the behavior seen in the link I provided?

Note: there's a Ext JS 1.x implementation of that lying around on this forum.
