HL7 in general business rules
I'm trying to create a general business rule, not an HL7 message router. (This is because i want to return values from the rules and message routing rules don't appear to be able to return values.) But, I want the business rules to be able to look at HL7 messages; I've copied a simple when condition from an HL7 message router but the error log throws up <PROPERTY DOES NOT EXIST> ...... *HL7
I'm guessing that because it's a general business rule the 'HL7.' syntatic shortcuts aren't available. Is there a way to switch these shortcuts on in a general business rule? I've tried setting the context class to EnsLib.HL7.MsgRouter.RoutingEngine, no luck.
Thanks

If you need to both route and take other actions based on data extracted in an HL7 message flow, you'll be better off doing it using a Business Process/BPL than a routing rule.
Thanks Jeffrey, these general business rules are to be used from a couple of BPLs, I already have the other actions and routing happening in these BPLs, it's just a case of getting the shared rules to inspect HL7
Replace HL7.{propertypath} with Document.{propertypath}. For example,
Document.{MSH:9}You will not have virtual property completion to refer to the segments/fields in an HL7 message, but you can continue to build your conditions in your HL7 message router and paste them in.
Thanks Shamus, I have tried Document.{etc} and get the same error as for HL7.{etc} :
ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zevaluateRuleDefinition+26 ^ full name of rule class.1 *Document, etc etc
my current workaround (which I'm somewhat uncomfortable with) requires an assign statement in those BPLs which reference the rules:
set context.HL7 = request
