Hi,

the below code returns e.g. [Node]. I want this returns Node instead of [Node]. What should I do?

e.refImmediateComposite().refImmediateComposite().targets -> select (t|t.name.name=e.lhs.target.name) -> collect (s|s.resolvedType.elementName)

I don't really understand but if you know your collection has only one element and want to return it outside a collection, just add ->first() at the end.

This is an old topic but can you please tell me, how to return multiple elements of collection as a single sttring. Like, from this collection {'Read', 'More',' to', 'Learn'}, I want to return 'Read More' as a single string.
