I try to keep it simple... I cannot assign my generated content (kind of string concatination) to the body of my JvmModelInferrer

Pseudocode:
counter = 0 //changing content
PMethod : {
	members += feature.toMethod(feature.name, feature.newTypeRef(Void.TYPE)) [
	  documentation = feature.documentation
	  
	  body = '''«feature.name»''' //WORKS (final variable)
          ###versus###
	  body = '''«counter»''' //DOES [b]NOT[/b] WORK (two pMethods will have same content!)
	  
	  counter++
	]
}


Am I doing something completely wrong here? Didn't evven notice that something is wrong until I tried two PMethods in my final project and noticed that they have the same content.

can you please share a complete minimal reproducing inferrer i wonder how this can compile at all since counter is not final

Need professional support for Xtext, Xpand, EMF?

I solved it. Seems as if you can't generate a string and just assign it to the predefined body variable inside the JvmModelInferrer. BUT you can create a feature.body variable through the *.xtext file like this
PMethod:
    'public' 'pFunction' name=ValidID '(' ')' '{' 
	    customBodies+=CustomBody*
	    body=STRING?    #<<<< I mean this
    '}';


and then assign the string to feature.body like so
feature.body = myBodyString


And assign this "helper variable" feature.body to the predefined body variable
body = '''«feature.body»'''


So instead of assigning myBodyString directly to body you assign it to feature.body and then feature.body to body.

I don't know if this workaround is intended to work this way but it does and that's all I need at this point ^^
