AEM Forms 6.5.17 - Index value out of range error
We were just updated from 6.5.0 to 6.5.17. We are unable to save or generate PDF preview for some forms, getting the log error "Index value out of range". There are no scripts on the forms. The error gives no indication of where the problem lies - no object or line info. Forms are also not, and have never been, attached to any kind of database. They are simply designed and published for the public to download. I tried copying individual objects into a new form, saving each time to see if I can isolate the error - no error was generated.
Please tell me there is a simple fix.
Oh, and this is only if saving the form as a static PDF, a must for the format we post our forms in. Dynamic does not seem to have a problem - but still can't generate PDF preview. If saved as XML form, it all works.
7/26: I have more info: The problem occurs when you have a grouping inside a List Item inside a List. Unwrap the List Item, and preview can generate OR Ungroup the grouped item, preview can generate. This does still seem like something that needs to be fixed.
