I also tried this patch :https://github.com/magento/magento2/commit/45ad72f562316e576438d1dcf45f64690510eab7
But after made changes run deploy clean cache.Then check it again while saving it re-direct to dashboard page.
So this patch also not working for me.
Please check this as i tired solution from here https://github.com/magento/magento2/commit/45ad72f562316e576438d1dcf45f64690510eab7
After using this patch it re-direct me on Dashboard page.
@nilesh2jcommerce We cannot reproduce this issue as described. Please provide the detailed steps we must follow to reproduce this issue. In addition, identify the web server you are running, the versions of PHP and MySQL, and any other information needed to reproduce your issue.
@nilesh2jcommerce I'd also check browser console (hit F12 to open it up) for errors on both the Console and Network tabs.
Please post a copy of trace or a screenshot of those (if any), as well.

Hi @magento-engcom-team,
If the description is correct, this seems to be a quite critical bug.
I assume it's still present on 2.1 branch - is that correct?
If so, please consider adding this bug as a known issue to the release notes of 2.1 branch and\or providing a timeline (or a milestone) for its planned resolution in 2.1 branch.
