Hello, I'm going to use

ViewersObservables.observeCheckedElements(...)

to get observable set of a CheckboxTreeViewer and bind it to my underlying model. However, the data in my model is a List not a Set.

say, myModel.getCities() returns a List object.

And,

bindingContext.bindSet( checkedObjTypes, new ListToSetAdapter( list ) );

seems not work.

So, what am I suppose to do to realize it? Thanks.

This would be the only solution and the correct one. Could you provide a
snippet we can use to reproduce your problem?

Hello, Tom

I found the real reason it does't wok is that there are more than one object type in my tree viewer. (content provider returns various typed children)

I want to bind the checked item of specified object type in the tree viewer to my underlying model.

So what should I do in this case?
