Editor Framework and Multi Select Listbox

Hello all,

I tried to implement a "MultiSelectValueListBox" based on the ValueListBox but I did not come far. Not even worth posting my messy code here :)

I hope anyone has done this already and can help me out on how to start or give some ideas how to approach this. I quickly ran out of ideas.

I am wondering why this is not shipped with the Editor Framework anyway and why no one seems to need this functionality? Googled a bit and only found one question on Stackoverflow regarding this. [1]

[1] GWT ValueListBox: can it support more than a single selection?

Regards
Alex
