cascading input control handle empty data...

[ronedog]

I'm using ireport 3.7.2 and jasperserver 3.7.0.  I got the Cascading Input Control feature working now and it works great when there is data for the succeeding controls. 

However, If I select something in the first parameter control (Which is a multi-select query), the second control (also a multi-select query)  then runs a query to return data for the 2nd list.  If there are no results to display for the 2nd list I get an error message box that pops up.  It's a blank message that just says "ERROR:" and that's it. 

How can I handle the situation when a 2nd or 3rd cascading parameter won't get populated because there are no results?  I don't mind if the control just stays empty, I just don't want the message box poping up.  Both the 2nd & 3rd controls are NOT manditory.

Thanks for the help.
