Greetings. I am using Drools 5.1.1's KnowledgeAgent ChangeSet functionality
and have come across an issue.
here is the use case:
Fire up the application with a valid DRL file. Works as designed.
Update the DRL file. ChangeSet senses updated file, KnowledgeBase is updated
with updated rules, yadda, yadda. Works as designed.
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:
KnowledgeAgent rebuilding KnowledgeBase using ChangeSet
[2010:11:308 09:11:515:info] KnowledgeAgent performing an incremental build of
the ChangeSet
[2010:11:308 09:11:843:debug] KnowledgeAgent has KnowledgeBuilder errors
object=Unable to resolve ObjectType 'Sccensor' : [Rule name='18) sensorCount
derived variable']
Rule Compilation error : [Rule name='18) sensorCount derived variable']
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (7:590) :
$masterID cannot be resolved
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (8:624) :
$masterID cannot be resolved
bass/enrichment/Rule_18__sensorCount_derived_variable_0.java (9:769) :
$masterID cannot be resolved
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.
Has anyone experienced this? Is there a listener that should be firing
somewhere?
Thanks is advance.
- Eric
