Joomla 2.5 How can I abort a save operation if there's an error?
===

Is it possible to abort a save operation in a Joomla controller? (Admin Side)

For example:
I have a view with a list of items. I hit the New Item button and in the next page I enter all required fields and hit save. My form also has a file upload field for uploading a small image. That image has to be 25 by 25 pixels or else the new item won't be saved.

The only way I found so far to abort the save operation (if an error like the image size is found) is to call the cancel() method **parent::cancel();** in the controller. This takes the user back to the list of items. I need to know if there's another method that will reload the **new item form view** with all the fields filled from the previous post so the user can just select a correct image and re-post the form without the need to fill all the fields from scratch.

Currently I'm fine with the cancel() method and if the user hits the browser's back button he will probably get back to the form with all the fields loaded, but I was just wondering if there is a way to reload the form.
