I am on BI 4.1 SP1 and build a report that has a Input Control that has a custom list of values. I use this to change the values in another variable. I have tested everything. I know that I only get this error when: I have the report set to Refresh on Open, in HTML viewer, and the first click on my report is this Input Control. If I use other Input Controls first, drill, or go to another report in the document first, the error will not. My problem is that our Executive want this to be the first page, view it in HTML, and I have to have it refresh on open. After you hit OK on the error, the Input Control works as expected.
Any thoughts or help would be appreciated.
