Hello Benoît,
I have to admit that I don't get your use case right. You want to use
"model.tree" on the first load as model for the tree controller and on
the second load, you want to use "model.tree.kids"? Do you want to set
the selection with the second bind? :
> this.store.bind('model.tree.kids', this.tree.controller,
> 'selection[0].kids')); // this would'nt work
Because thats what the code tries to do.
Perhaps you could tell me what you want to achieve with the code?
Maybe i can help you more if I know what you want to do.
To your second question: You can just change the model and the data
binding will populate the the tree. As the model is a set of qooxdoo
objects with data arrays, you can just manipulate these model objects
and that should do the job. :)
Best,
Martin
