[jdt-dev] AST rewrite on other AST.

[Kenneth Styrberg <kenneth@xxxxxxx>]

Hi, I'm trying to fix a bug where a modification needs to be done on a 
Node (oldNode), that is in another CompilationUnit currently not in 
scope for the ChangeProposal.

Currently I tried with:

    ASTNode newOldNode= ASTNode.copySubtree(newNode.getAST(), oldNode);

to create the newOldNode and connect it to the AST, but if I add changes 
to newOldNode it doesn't update the CompilationUnit.

I've also tried with:

    CompilationUnit oldNodeCompilationUnit= 
ASTResolving.findParentCompilationUnit(oldNode);
    ASTRewrite oldNodeRewrite= 
ASTRewrite.create(oldNodeCompilationUnit.getAST());

and work with oldNodeRewrite, but that doesn't work either.

I've read the article "Abstract Syntax Tree", and it states to use a 
TextEdit and manipulate files using ITextFileBufferManager, But I hope 
there a a shorter path to do what I want.


All help appreciated.

Regards,

Kenneth
