hi.
I want to call for a Java function in template, according to the related docs, firstly, I wrote the following code:

List[Entry<Integer,Integer>] funcname(paras)
...

then I wrote the function in another java file:

public List<Entry<Integer,Integer>> funcname(paras)
...

the return value I expected should be pairs of number, such as: 2, 3 or 3, 1.

however, in the .ext file, I got a error message:
mismatched input '<' expecting ']'

could you give me some suggestion?

Hi,

xpand/Xtend does not support nested generics so the returntype might be simply List[Entry]. At runtime you may Be able to downcast when iterating over the List.
