We just discovered a change in behavior in version 2014.1.403 of the editor. Our previous production version of the editor was 2012.2.724 - it did not have this problem. I have not tested any other versions of the editor besides these two. I reviewed the release notes and saw nothing to indicate this was an intentional change.
To demonstrate the problem, I created a simple project with a single aspx page that includes an editor and a submit button. I'll include the markup below. The submit button does a redirect.
The problem we are seeing in version 2014.1.403 of the editor is that if the user clicks the browser Back button after the submit, their updated editor content is GONE. This problem did not exist in 2012.2.724. In 2012.2.724 any content entered by the user was retained upon clicking the Back button.
Note that other controls on the page all retain their updated content upon Back button click.
I've created a small video to demonstrate the problem. Please watch it here:
The previous editor behavior is depended on by our application for handling concurrency scenarios. This is affecting our production customers now.
Is there some way we can achieve the previous behavior in the 2014.1.403 editor? Otherwise, can we get a fix included in the next release of the editor?
