[news.eclipse.tools.jdt] Re: Using the ASTParser for parsing an expressi

[judith.wiesinger@xxxxxxxxxxxxxxx (Judith Wiesinger)]

Hi,

I have tried to parse the expression wrapped in a compilation unit. See 
the following code but the type binding is still null. Does anybody know 
why? How can I get to the type binding?

Thanks for your help.

ResourcesPlugin.getWorkspace().getRoot().getProject(projectName);
       IJavaProject javaProject = JavaCore.create(project);
       boolean exists = javaProject.exists();   // project does exist
       parser.setProject(javaProject);

           + "public static void myMethod() { \n"

       ExpressionStatement stmt2 = (ExpressionStatement) 
                 block.statements().get(1);    // stmt2 = "i=5 + 4;"
       ITypeBinding typeBind = stmt2.getExpression().resolveTypeBinding();
       // typeBind == null ????
