Thanks Alexander!
I have used your idea and i have component already working! :) I just need
to add a validator and that's it. Hopefully i will have time to finish it
tomorrow so i will post the code to show the t5 way (And it's quiet easy!:)

Well, here is the code. If you need comments, the whole issue will be
published soon, hopefully on the next week. That will be #14, and there are
three other issues to be published before it:
#11: DatePicker and Shell
#12: PropertySelection and IPropertySelectionModel
#13: Autocompleter and InlineEditBox
Cheers,
Alexander
