Hi Alex,
I am using the latest version of DFFS. I have rules which hide/show a tab based on 3 conditions, whether the user is the author, whether user is in a specified SharePoint group, whether user is in a people picker field in the form. The identical rules work perfectly in the Edit form, but not the display form. When I turn on the debugger for the rules, it tells me they are processing and the tab is visible, however, the tab is still hidden. I am wondering if this is a bug? I had a similar issue a few days ago with the Display form and deleted the form and started over. Here is a screen shot that says the tab is visible, and the form tabs.
Thanks for your help!
Kim
