#1 Error in ScriptletCompletionProcessor.java

[Arne]

Line 223: codeComplete(fCollector);

shows error:
The method codeComplete(ICompletionRequestor) in the
type ScriptletCompletionProcessor is not applicable for
the arguments (ResultCollector)

Should I cast fCollector to:
codeComplete((ICompletionRequestor) fCollector) or what
is the Errorcorrection?

Thanks
Arne
