Thanks Richard,
That seems to be the problem.
What I was telling in my earlier mail is that the javascript binding seems
to have a similar problem with plasmoid.dataEngine("engine
name").serviceForSource("source name") and maybe they solved it by
implementing the service function: plasmoid.service("engine name", "source
name") (and method Plasma::Applet#service is not implemented in ruby ) .
