Inherited EditorServerCommandAction double posts returnMessage

Question

I have a bunch of inherited EditorServerCommandActions in my WebADF solution and when ever I use the ReturnMessage inside EditorServerAction() it generates two javascript popups at the clientside.

Is this a common know error or am I simply missing something?

public class CustomCommandAction : EditorServerCommandAction
{
    protected override void EditorServerAction()
    {
        ReturnMessage("Foo");
    }
}

Answer 1

I know this might sound obvious, but is something calling that routine twice? If you set a break point at ReturnMessage is it hit twice? If so, you could dig into where it is coming from. Perhaps there is more than one instance of the CustomCommandAction somehow.
