Is there an effective way of using GWT's FormPanel to post an array of values to a servlet? It's related to a file upload widget so I need to do this via a standard HTTP request rather than an RPC. The idea is that in addition to posting the file, the user can select several options as meta data. These options ideally take the form of 3 arrays containing 1 to N items each. I've so far been able to post to the servlet single selections for the 3 options using Hidden items which are attached to the formpanel. Is there a control or widget or whatever that allows me to send arrays? Thanks
