Jozef, have you gotten around the problem of a double click to get back to the original form state. Here is my problem. Whenever I use ctx.responseComplete() it always seems to mess with the state of the application. By that I mean when I click the button the first time it submits the form and executes and displays the new page just fine. But when I go back to the parent page and click any button on the page it does a full trip to the server without executing the action method. Then the second time I hit the button it works just fine, but then ctx.responseComplete() is executed again and the cycle starts all over again.
The only way I have been able to get around it in some instances is to use a commandLink tag and do a target blank to a jsp page that reads in url parms and determines what it needs to download. This works because I never run the ctx.responseComplete() method. Does anyone know if responseComplete() has a bug in it, or if we are using it incorrectly?
