####################END JAVA CLASS FILE ##########################
I'm using Drools 4.0.7
The problem is, that many activations are create (one for every
EstimatedElectricUsage) everytime I retract the first object from the
working memory (lines 45 and 53) You can see the activations created, and
immediately cancelled, in the file event.log attached to this post.
http://www.nabble.com/file/p23381763/event.log event.log (open this file in
the Audit View of Eclipse Plugin for a better read)
If I put the "lock-on-active true" for rule "Get total Capacity
factor" then
activations are not created when corresponding objects are retracted (line
45, 46) but It doesn't work for rule "Get total Transmision factor". See
event2.log file for detail. http://www.nabble.com/file/p23381763/event2.log
event2.log
Adding "lock-on-active true" for rule "Get total Transmision factor"
doesn't
resolve the activations for lines 53 and 54.
When the objects are retracted none of the rules should get activate,
becaouse the rules depend on the existance of the objects retracted.
finally, sorry if my English is not so good, Ask me, If you have any
question to clarify mi problem.
This is my example project if you want to reproduce the case.

After hours loking for a solutions I finally found it. I had to avoid using
"from" in this case, according to recomendation that I found in this
http://www.nabble.com/Rules-with-from-always-loops-(Drools-4.0.7)-td21930...
Message
So, I retired from my rules sentences like:
usageItem: EstimatedElectricUsage() from
account.getElectricUsageEstimation(1,6);
And I had to insert each EstimatedElectricUsage object directly in the
working memory.
