Subject: [PATCH] Fix injection on Form posts

In use with Silvershop, a form post from the AddProductForm would pass the form trough the `afterCallActionHandler` as the `$result`. This causes the `getValue` to error. By checking if the result is an instance of `DBHTMLText` this error can't happen anymore.
