The following xtend code

for ( n : someElememtList.map( e | e.name ).toSet ) {
	for ( e : someElememtList.filter( e | e.name == n ) ) {
		// ...
	}
}

is accepted in the xtend editor, but leads to the Java error message
Quote:

Cannot refer to a non-final variable n inside an inner lass defined in a different method

which is caused by a Java restriction on closures.
Is there a workaround for this kind of nested loops with closures in xtend?

Hi, what about

for ( n : someElememtList.map( e | e.name ).toSet ){
    val n2 = n
	for ( e : someElememtList.filter( e | e.name == n2) ) {
		// ...
	}
}
