Hello,
Using Xtend2, the following line:
'foo,bar,baz'.split(',').reverse().join(',')
generates the following Java code:
String[] _split = "foo,bar,baz".split(",");
List<String> _reverse = ListExtensions.<Object>reverse(((List<String>)Conversions.doWrapArray(_split)));
String _join = IterableExtensions.join(_reverse, ",");
return _join;
with exception: The parameterized method <Object>reverse(List<Object>) of type ListExtensions is not applicable for the arguments (List<String>).
There appears to be an issue with type inference using that many extensions in one expression.
Edit: Ok, perhaps not an issue with ListExtensions specifically, but rather with the code generation and use of ListExtensions.
