Description Moritz Eysholdt CLA 2011-04-07 08:57:59 EDT 
with java class 
-------
public static Map<IConstraint, List<EObject>> getGrammarConstraints(Grammar grammar, EClass clazz) {...}
public static Collection<IConstraint> getGrammarConstraints(Grammar grammar) {...}
-------

the xtend2 code 
-------
grammar.grammarConstraints(clazz)
-------

erroneously binds to getGrammarConstraints(Grammar). It should link to getGrammarConstraints(Grammar, EClass).

the java class is made visible via "import static extension"
Comment 1 Sebastian Zarnekow CLA 2011-04-07 08:59:33 EDT 
Is the binding wrong (e.g. the generated code is wrong) or is it the hyperlinking, that does not work?
Comment 2 Moritz Eysholdt CLA 2011-04-07 09:05:25 EDT 
the hyperlinking leads me to the wrong method. So I assumed the binding is wrong.

Some more playing around shows that the java-method getGrammarConstraints is only made available as "grammarConstraints" if it only has one parameter. If it has two parameters, only "getGrammarConstraints" is visible.
Comment 3 Moritz Eysholdt CLA 2011-04-07 09:06:19 EDT 
grammar.getGrammarConstraints(clazz) binds as expected to getGrammarConstraints(Grammar, EClass)
Comment 4 Sebastian Zarnekow CLA 2011-04-07 09:43:17 EDT 
A short offline discussion revealed a usability problem with respect to the content proposals in Xtend. The linking and navigation is correct.
