After upgrading to form NAV2016 first release to CU09 I have been getting this error with some users when hitting some actions in some pages.
I have reset all their customization, I have re-compiled objects, delete zup files... and I have solved the problem with all of them... but one!
The problem is kind of tricky since it happens sometimes (executing different actions) but, if the user tries like 5 minutes later it works fine which is absolutely weird.
Of course, other users executing same action in same page don't get this error... just this man...
Any suggestions?
