Robert,
I am still trying to correct the issue I am having with hyperlinks in a related table. After days of pounding my head on the table and trying everything I can think of, I have more information but still no solutions. I believe the issue has something to do with having the feature class and the table tied together with a relationship class. When I exported both the feature class and table to shapefile and made a test service and application, it resolved the white screen and loss of functionality but throws an error stating "invalid or missing input parameters" (even though the hyperlink works perfectly). Does this added information give you any ideas on what the issue could be and I am also wondering if you tried the relationship class when you were trying to replicate the issues?
Thanks,
Casey
