I have a report with a drop-down list param that has two options, "Summary" and "Detailed". It loads into Detailed view by default and works fine then. If I switch it to Summary view it also works fine. BUT if I switch it back to Detailed, then it stays in summary view no matter what. It looks like the issue is basically that if a parameter value is selected for a second time, then it doesn't load a new report for that new parameter change. I create the parameter programmatically in the constructor. Anyone know what may be going on?
