AdapterFactoryTreeEditor or IUpdateableItemText not notifying editor of change [message #417475]

I'm trying to use the AdapterFactoryTreeEditor to change the names of
items in my tree.

I've got as far as implementing the IUpdateableItemText in my ItemProvider
(together with adding IUpdateableItemText to the supportedTypes in my
ItemProviderAdapterFactory).

Whilst I can now edit the names in the tree, the editor doesn't seem to be
notified of any change, so the save menu item isn't enabled (the save As
menu item is enabled however).

Does anyone know if there's something else I need to add/change?

Gemma,

Are you using a command and executing it on the command stack to apply
the change? That's very important and it sounds like you've applied the
change directly to the model without doing that...

Hi Ed,

After some further investigation I think I might have found the problem.
Previously in my setText method (in my ItemProvider) I was doing something
like:
public void setText(Object object, String text) {
object.setName(text);
}
whereas I've now changed it to:
public void setText(Object object, String text) {
setPropertyValue(object, "Name", text);
}
Am I right in that by doing this I'm triggering the necessary command you
mentioned?

Gemma,

Yes, if you are going through a property descriptor's implementation, it
should properly construct a command and execute it.
