Re: [qooxdoo-devel] How to use data binding for a SelectBox (which is intended for single selection)

[MartinWittemann]

Hi,
the model is available via closure in your example. Just paste my code unter
your code postet some mails ago and its working. 
It's a good question of how to handle such a mix of model data. I haven't
thought of that because my mind was always using only "data models". 
Maybe i come up with a solution tomorrow. :)
Best,
Martin
