resolveBinding return null [message #808113]

I am trying to get method binding from javascript source file. What I do is to set up the parser as follow:

ASTParser parser = ASTParser.newParser(AST.JLS3);
parser.setKind(ASTParser.K_COMPILATION_UNIT);
parser.setResolveBindings(true);
parser.setSource(source);

JavaScriptUnit unit = (JavaScriptUnit) parser.createAST(null);

and then I add a visitor to the "unit" to visit FunctionDeclaration. Inside FunctionDeclaration I try to get resolveBinding, but I get null.

Which part is wrong? How can I get method binding?

Thanks in advance,
Alireza

What was "source" here?

The source is char[] that I read from js files. I use a visitor class to visit FunctionDeclaration and it works perfectly fine. The problem is with binding that returns null.
Any thought on that?

You have to set the project on the ASTParser, or otherwise use a real
file that's in a project's Include Path--otherwise it has no idea where
to look for even the built-in runtime objects.

Actually I sent another post about how to create a IJavaScriptProject and still I did not get a good answer. What would be the easiest way (assume I put all my files in a folder with name "jsfiles")?

I added the folder with javascript files to my include path in eclipse but still the bindings are null.

Hi
I have a same problem!
I can read function using "FunctionDeclaration" but I want to access to variables in my java script code. I use "VariableDeclaration"! It doesn't work, and returns null.
Can you help me.
Thanks :)
