Hi all,

I have implement TreeViewer(GEF) in my Editor,
and create a PaletteView(extends ViewPart) for my editor.

In PaletteView here are some Entry can add to my TreeViewer.
So the PaletteView just like GEF Logic Example Editor's Palette.

But when I select a Entry and move mouse to my TreeViewer,
I got the NO icon, can't add the entry to the TreeViewer.

What's wrong?
Have any hints?

Thanks.

Well, I know what's wrong with it.
TreeContainerEditPolicy#getCreateCommand(CreateRequest) method must
return a command, but I return a null.
So I always got NO icon.
