We have a webdev 17 website.
This is functioning good.
Except one customers keeps getting failures when using the site. (more then 1 user)
They get the following error at rondom when using the website

Unable to perform the requested action, The browser [BACK] or [NEXT] button has been used on a page containing dynamic data. Data displayed is no longer consistent with data processed.

This is in IE8 but also in the latest chrome version.
Any body any suggestions ?

We had this issue as well.
This occurs when the user pressed the back button on their browsers.

We believe it has to do with WebDev preventing the back button being used(A page option as well as a project description setting).
WebDev injects
<SCRIPT LANGUAGE="JavaScript">
history.forward()
</SCRIPT>

into the html when the HTML page is generated which to my knowledge, is the equivalent of pressing the back button and then pressing the forward button again. Or also your pages might deal with the back button by using synchronization code which we have tried and hasn't helped us either. You can see information on it in the docs under "Preventing from using the Back key"

Our solution to this problem was to catch the exception at a project level and redirect the user back to the login. Since the session and all the user info is destroyed when the exception is thrown. Let us know if you come up with a better one :)
