Forwarding from aspectj-users, since I didn't get any response there, may this would be a better place to try.

Hi all, I'm trying to create an AspectJ AST using the API from org.aspectj.org.eclipse.jdt.core.dom.

When I try to modify the "aspect" property of an AjTypeDeclaration I'm getting the following exception:

java.lang.IllegalArgumentException: AjTypeDeclaration has no property aspect

    at org.aspectj.org.eclipse.jdt.core.dom.ASTNode.setStructuralProperty

(ASTNode.java:1545)

The code that raises this exception is the following

    //after creating the parser and getting the CompilationUnit...
            AjAST ast = (AjAST) aspectAST.getAST();

            AjTypeDeclaration aspectDeclaration = 
ast.newAjTypeDeclaration();
            aspectDeclaration.setStructuralProperty(
                    AjTypeDeclaration.ASPECT_PROPERTY, true);

I tried changing to AspectDeclaration, but it raises the same exception, and I also tried using the setAspect() method, but with no success.

Any thoughts?
