Indeed, "Direct Edit Label" is the right way to edit and save the edited
value. [1] Use a "Set" operation to set the edited value on the feature.
But be careful, in Value Expression, use an expression like [arg0/] and
not $0 as it is wrongly indicated in the tooltip of "Edite Mask
Variables"/Mask is wrong.
About the NPE, could you provide us data to reproduce the issue and also
your complete stack trace.

Yes thanks. I would be pleased if you could provide me the stack trace.
You can get it clicking "Details" when the pop up is displayed or in
"Error log" view.

Laurent
