Jasper Server Input controls don't execute

[hal_1]

I've been using Jasper Server for about 3 years and have successfully created many reports that use input parameters. Simple one and multi-select cascading input parameters.

I've started having an odd problem when executing the reports from jasper server.  When I'm in ireports, I have a connection to my server and can run the reports from the server. The reports execute properly, the cascading input parameters work great.

The problem is when I run the report in jasper server.  I log in, select the report and the parameters may not even execute.  Sometimes they will execute and I select the 1st input control. The 2nd input executes a query based on the first entry. The 2nd query does not execute the query so I can't select the input control for the 2nd input control.

In other cases, the input controls don't display at all.

These are reports that have worked in the past but for some reason aren't working.

Is there something I can check with the server that could cause this problem?
