refactor ----CopyParticipant failed problem [message #510755]

I have a class extends org.eclipse.ltk.core.refactoring.participants.CopyParticipan t class.
so there will be three method in my class. they are :
protected boolean initialize(Object element) {}
public RefactoringStatus checkConditions(IProgressMonitor pm,CheckConditionsContext context){}
public Change createChange(IProgressMonitor pm){}

Everything seems Ok if I copy a file to another folder, that means my own code in three methods above can be executed.

the problem is that my code can't be executed if I want to copy and paste a file to the same folder. in this case, there will be a Name conflict dialog which we need to input a new file name, then the paste action will finish without entering my CopyParticipant, even the initialize method in my class is skipping, this is very confused.

the eclipse version is 3.2.2.
Any one can give me some comment about this?

thanks,
ping

Hard to say. There's just too little information in your post. The best
thing you can do is to file a bug report against JDT UI with your full code.

The Problem is, that you have to create a Change in your createChange() Method and not using the method for the refactoring itself. You also have to check all possible failures in your checkConditions() method.

When you return the Change Eclipse will then do the refactoring with its own code and then call your changes perform() method.

What I didn't find out was that when the filename changes, how you get the new filename from the dialog......
