But now that you mention it... I see that there is some big difference in
ClassHelper.make(String) and ClassHelper.make(Class) - regarding generics,
ClassNode construction and similar.If I use the overriden method with a Class
argument then the error is gone. But I am still slightly confused as why the
different behavior?

Hi Cedric,
well first in the method where I transform the MethodCallExpression I use this:
ClassHelper.make(returnType) where 'returnType' is the String
"org.apache.commons.lang3.tuple.Pair" and after this in my
visitDeclarationExpression (as I am in a Visitor) I use this ClassNode to
create the CastExpression.

Hi Anton!
How, in your AST transformation, do you create the class node for `Pair`?

Hello,
I have a DSL and some AST transformations. Now I would like to include some 3rd
party classes in my DSL. For example some apache commons lang classes like
Pair, etc.
In my language I offer the user the "bar()" method (which I have defined
elsewhere). However the "bar()" method is just for user's convenience. Actually
I am calling the "bar2()" method under the hood - this is why I have the AST
transformation.
So writing:
def foo = bar()
Becomes:
def foo = bar2() as Pair
Now consider this AFTER transformation statement:
def foo = bar2() as Pairfoo.getKey()foo.getValue()
Having the @TypeChecked annotation I get this error: Cannot find matching
method org.apache.commons.lang3.tuple.Pair#getKey(). Please check if the
declared type is right and if the method exists.
But if I write something like:
def foo = Pair.of(3,4)foo.getKey()foo.getValue()
Then everything is fine. Is there something that I am missing. What is even
more weird: I have my Type Checker extension and I see that
"handleMissingMethod" is called for "foo.getKey()" so at this point I try to
resolve the statement by myself but calling "...getDeclaredMethods(..)" returns
an empty list.
Best regardsAnton
