Crystal Report in JSF not refreshing with new parameters

[Jen Gordan]

I am trying to show a Crystal Report from my JSF program using this code in my jsp:
<hx:scriptCollector id="scriptCollector1">
<h:form id="form1" styleClass="form">
<bocrv:reportPageViewer
reportSource="#{reportWrapper4.reportSource}"
viewerName="CrystalViewer"
allowDatabaseLogonPrompting="false"
databaseLogonInfos="#{pc_myReport.conInfo}"
allowParameterPrompting="false"
parameterFields="#{pc_myReport.param}"></bocrv:reportPageViewer>
</h:form></hx:scriptCollector>
The first time the report runs the parameters are set fine and the report shows correctly. When I close the report and select new parameters and run the report again, the report runs with my old parameters. Has anyone else run into this problem?

Thanks so much.
Jen
