New Oracle attributes added in BPM are not retrieved by Oracle

Hi,

We have added 2 new Oracle attributes (both at the Header level) in some existing rules of our PO Workflow ("isChangeOrder" and "approvalTotalPercentageChange") but when we test these rules with these 2 new attributes, the workflow failed with the following error "Validate the BPM rule for PreApprovalFirstResponderWinsRules and ensure it returns a valid approval hierarchy".

When we look at the diagnostic log, i see these 2 attributes in the rules modified (as expected) but when i look at the Fault Payload in the diagnostic log, it looks like Oracle doesn't try to retrieve the current values for these 2 attributes through the "findAttribute" command like it does for the other attributes used in rules.
