Hi @srowen , The current behavior of WEBUI is,
1) When user enters a page size more than current page size, It falls back
to first page (In all the pages)
2) When the user enters a page more than the maximum page number, page
navigate to first page but throws an exception.
After the PR,
1) Behavior is same as before
2) Instead of throwing exception, page falls back into first page and
display it contents.
> Returning to the current or last page seems fine too. No error message
really needed IMHO.
Returning to current page seems more code change is required. Because we
are getting all the parameters related to page from the url. Currently we are
not passing any parameter to get which page he was previously.
Also to make it consistent with the page size behaviour, we can return
first page.
