I tried to build a palette view with paletteviewer in a standard eclipse
view.
The problem i faces is that when i have a palette entry selected in that
view and i close the editor. I tried to repopulate the paletteroot and set
it to the palette view. I faced a error message as following. I guess this
is becuase the activeEntry is not be resetted when the palette root was
setted to a new one. Am i right?
i call this method to set the new palette root:
PaletteViewer.setPaletteRoot(root);
java.lang.NullPointerException

Thanks very much.
removing all children is a good idea.
As you guessed, i want to share the same palette across different editor
instance. I'd like to create different palette view when different editor
was opened. Same type editor will use on palette.
