Hi, I have been working on this one for a couple of days left and can't figure it out. Simple case, I have a report and I am trying to create a drill down to another report. I have read the forums and it seems quite simple. I am using the "reference" as my hyper-link type. When I run the report hit the link, I get one of two problems. One: Null URI (So this means I have linked it wrong. Not really a big problem) Two: I get this error: org.springframework.webflow.engine.NoMatchingTransitionException: No transition was matched on the event(s) signaled by the [1] action(s) that executed in this action state 'checkForParams' of flow 'viewReportFlow'; transitions must be defined to handle action result outcomes -- possible flow configuration error? Note: the eventIds signaled were: 'array<String>['error']', while the supported set of transitional criteria for this action state is 'array<TransitionCriteria>[[eventId = 'yes'], [eventId = 'no']]' I guess the question is, do I need to link to a jasper sever report, or to a jrxml file resource. This is the xml from the hyper-linked field: <textField isStretchWithOverflow="false" isBlankWhenNull="false" evaluationTime="Now" hyperlinkType="Reference" hyperlinkTarget="Blank" > <reportElement x="0" y="0" width="100" height="18" key="textField"/> <box topBorder="None" topBorderColor="#000000" leftBorder="None" leftBorderColor="#000000" rightBorder="None" rightBorderColor="#000000" bottomBorder="None" bottomBorderColor="#000000"/> <textElement> <font/> </textElement> <textFieldExpression class="java.lang.String"><![CDATA[(($F{program_name}!=null) ? $F{program_name} : $F{training_award_types_description})]]></textFieldExpression> <hyperlinkReferenceExpression><![CDATA["http://appserver-prod.lesmills.net.au:8083/jasperserver/flow.html?_flowId=viewReportFlow&reportUnit=/testing_links_report.jasper"]]></hyperlinkReferenceExpression> </textField> I hope someone can help me on this one. It looks so simple and I know I am doing something stupid, but what is it?
