Re: [qooxdoo-devel] SelectBox and DataBinding (round 25)

[Guilherme A. <gr...@gm...>]

Right, Eduardo.

That would solve my problem.

If modelPath is not set then the whole object is what you want to get (just
like you have today).

Setting modelPath to "id" should then set the widget children model too:
listItem.setModel(objectModel.getId());

So many questions about simple data binding problems should be considered
warnings that something should be done. I mean, the whole data binding stuff
is great, powerfull and well-thought. But it seems that an even higher
abstraction layer is needed, at least default converters for those cases
that you use everyday.
