JBPM throws following exception while evaluating expression using bpws.getVariableData in predicate - | 2007-09-10 11:24:13,233 DEBUG [org.jbpm.bpel.graph.basic.assign.FromVariable] evaluating query '/ns9:GetItemsByQueryResponse/ns9:return[bpws:getVariableData("index")]/ns9:genericItem/ns9:itemID' for 'Token(/primary)' | 2007-09-10 11:24:13,264 DEBUG [org.jbpm.bpel.graph.scope.FaultActionHandler] handling fault exception: org.jbpm.bpel.graph.exe.ScopeInstance@13fb60f[name=global,token=/,state=ScopeState[performingPrimaryActivity=0],id=0] | org.jbpm.bpel.graph.exe.BpelFaultException: org.jbpm.bpel.graph.exe.FaultInstance@82bb3d[name={http://schemas.xmlsoap.org/ws/2004/03/business-process/}subLanguageExecutionFault,id=0] | at org.jbpm.bpel.sublang.xpath.XPathQueryEvaluator.evaluate(XPathQueryEvaluator.java:62) | at org.jbpm.bpel.graph.basic.assign.FromVariable.extract(FromVariable.java:65) | It seems queries can be 'GetVariableDataFunction' or 'Pure XPath'...but I thought this would be a common case where inside while loop user would want to iterate over one record at a time. Are there plans to support this? Shall I enter JIRA issue? Thank you, Meghana. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082738#...
