[jboss-user] [JBoss jBPM] - bpws.getVariableData as predicate is not supported?

[meghanai_99]

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)'

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.
