I have a pretty simple rule that matches a pair of facts, each with a
different name. Facts are named and also have a namespace, which allows
for a qualified name of the form <namespace>:<name>. I'm testing for
specific names. When both patterns use the same slot (name or
qualifiedName), the rule does not match. But if I use the qualifiedName
slot on one and the name slot for the second, it works. Can anyone point
me in the right direction for things to look at? It feels like the Rete
network is confusing the two cases when in fact they are different.

I have a small set of facts I'm testing with. One DataUnit which has
two associated MetricValues and one orphan Metric Value.

f-4 (MAIN::MetricValue (attributeCount 1) (attributeValues
<Java-Object:java.util.HashSet>) (attributes
<Java-Object:java.util.HashSet>) (class <Java-Object:java.lang.Class>)
(dataUnit <Java-Object:com.ims.pharmetrics.qaf.core.DataUnit>) (savg
<Java-Object:com.ims.pharmetrics.qaf.core.SAVG>) (segmentation
<Java-Object:com.ims.pharmetrics.qaf.core.Segmentation>) (unsegmented

(name "Threshold") (namespace
<Java-Object:com.ims.pharmetrics.qaf.core.Namespace>) (property FALSE)
(qualifiedName "PMPM:Threshold"))
I have the following rule:
(defrule TestRule
?du <- (DataUnit (name ?du_name) (OBJECT ?du_obj))
(MetricValue {qualifiedName == "TEST:RecordCount"} (dataUnit
?du_obj) (OBJECT ?foo_obj) )
(MetricValue {name == "Threshold"} (OBJECT ?bar_obj) )
=>
(printout t "Evaluated " ?du_name " crlf))
This works fine (fires twice). It also works if I change it so that the
second MetricValue has a qualifiedName and the first does not.
(defrule TestRule
?du <- (DataUnit (name ?du_name) (OBJECT ?du_obj))
(MetricValue {name == "RecordCount"} (dataUnit ?du_obj) (OBJECT
?foo_obj) )
(MetricValue {qualifiedName == "PMPM:Threshold"} (OBJECT ?bar_obj) )
=>
(printout t "Evaluated " ?du_name " crlf))
But when I use change the MetricValue tests to both use the same slot ,
I get no matches. e.g.
(defrule TestRule
?du <- (DataUnit (name ?du_name) (OBJECT ?du_obj))
(MetricValue {qualifiedName == "TEST:RecordCount"} (dataUnit ?du_obj)
(OBJECT ?foo_obj) )
(MetricValue {qualifiedName == "PMPM:Threshold"} (OBJECT ?bar_obj) )
=>
(printout t "Evaluated " ?du_name " crlf))
