Data Shows in Subreport but not Master Report

[cschnell]

I have a table in a sub report.  If I preview the subreport, it shows the data in the table.  If I run the subreport on the server it does not show the data in the table, but all other data in the subreport is fine.  Same if I run a preview of the Master Report.  On the other hand, the same table was used straight in a master report and did not show the data.  I only have one parameter I'm passing down and I must be passing it okay if the data does show in the one.  So what else could be stopping the data from showing?

While I thought I had my parameters mapped, apparently you also need to have the below parameter in the "Parameters Map" expression.

$P{REPORT_PARAMETERS_MAP}

After I added this, it worked.
