Hi Boosie,
Sorry to see that the cloud is having a thunderstorm...
Did we talk about this yesterday? If not, sorry for confusing you with someone else.
I just tested a blank filler form with qRules v5.1 on O365 and this is working as expected. If you can use filler (as a workaround), please reinject with qRules v5.1 and republish.
Microsoft did upgrade O365 on Wednesday (without notifying people) and that broke code behind in the browser.
I just retested browser code behind on O365 and it is still broken. SIGH!
