<br>
here is the use case:<br>
<br>
Fire up the application with a valid DRL file. Works as designed.<br>
Update the DRL file. ChangeSet senses updated file, KnowledgeBase is updated with updated rules, yadda, yadda. Works as designed.<br>
Update the DRL file and introduce errors in the LHS of the rule. For example, I changed Sensor to Sccensor in the example below and $masterId is not defined. The following is reported as expected:<br>
<br>
KnowledgeAgent rebuilding KnowledgeBase using ChangeSet<br>
[2010:11:308 09:11:515:info] KnowledgeAgent performing an incremental build of the ChangeSet<br>
[2010:11:308 09:11:843:debug] KnowledgeAgent has KnowledgeBuilder errors object=Unable to resolve ObjectType 'Sccensor' : [Rule name='18) sensorCount derived variable']<br>
Rule Compilation error : [Rule name='18) sensorCount derived variable']<br>
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (7:590) : $masterID cannot be resolved<br>
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (8:624) : $masterID cannot be resolved<br>
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (9:769) : $masterID cannot be resolved<br>
<br>
Update the DRL file to the previously working version. The ChangeSet never senses that the file has been updated. It just runs along checking every x seconds.<br>
<br>
Has anyone experienced this? Is there a listener that should be firing somewhere?<br>
<br>
Thanks is advance.<br>
<br>
- Eric<br>
