Hey, I don't see a bug in that code but something that might need some explanation. Here is, step by step, what the code does if you give the delegate.
Line 1-14 You set up the data binding via controller and use the default binding for the label. Line 15-19 The Delegate will be set but the bindItem method is empty which means it renews the bindings based on the given delegate method. During that, the old binding will be removed, only the values of the widgets will not be reset (in a regular case, they will be overridden anyway). This can be verified by changing the original model and check if the label in the selectbox changes. Line 22-34 You change the model and the binding will be set up once again, but with the same result, nothing changes. In the end, if you want to use the bindItem delegate and also want to have the default binding for e.g. label, icon and model property, you have to call the "bindDefaultProperty" method in the bindItem method. :) I hope that mad it a bit clearer, Martin Am 20.12.2012 um 16:48 schrieb loremipsum <[email protected]>: > Hi folks, > > I've found a strange behavior.
