Hi all,<br>
<br>
Our object deals with the clinical domain. We have a class LabEvent that<br>
represents a visit in the laboratory. Each event is associated (using the<br>
laboratoryResult association) with one or more LabResult objects (children),<br>
each represents the results of a particular test.<br>
in the rule LHS we want to express the following condition:<br>
"At least two LabEvents in the last month, with a LabResult with value<br>
greater than 1.8"<br>
of note, the application asserts the LabEvent objects to the workingMemory.<br>
<br>
in DRL we tried to write it as:<br>
ArrayList(size>1) from collect(<br>
LabEvent(eval( dateWithinLastMonths(effectiveTime,1)),<br>
results:laboratoryResult)<br>
LabResult( value >1.8) from results)<br>
<br>
Of course, the problem is that collect expects a single pattern...<br>
<br>
Does anyone has a simple idea how to express this business logic?<br>
<br>
Thanks, Yoni<br>
