Hi All..
I'm working on an RCP app that has a view which lists items in a
TableViewer.
The view is backed by a model which is provided as a service by OSGi
declarative services, and so typically it may or may not available.
My problem is that when the model turns up in my ServiceTracker, and I
call setInput(model) and then refresh() on the TableViewer, my View does
not refresh itself.
In the ContentProvider I can see that inputChanged() is being called,
but not getElements().
I'm not sure if I've approached this the right way, but it's certainly
not working as I expected.
Anyone have any insight on this problem?
Cheers,
Sean

Thanks, I did, still no luck, although it did get me past the thread
access exception I didn't realise I was having. I hate how all these
exceptions are quietly hidden away... is there any way in the PDE to
make exceptions a little more noticeable?
Cheers,
Sean

Store the input object in Vector or ArrayList. Then set the vector/arraylist as input. Check for the instanceof of the input element in getElements method as in the following code. Make sure that the methods in label provider also checks for instanceof input element.
public Object[] getElements(Object inputElement) {
ArrayList<Object> objList = new ArrayList<Object>();
if (inputElement instanceof Vector) {
objList.addAll((Vector) inputElement);
}
return objList.toArray();
}

Make sure that the methods in label provider class also checks for instanceof of the input element before retrieveing the data.
