Hi jess-users.
We have developed an intelligent agent architecture whose reasoning
capacity is given by JESS. The architecture was developed with JESS 4.x
version and all seems to go well.
Now we are trying to change from version 4.x to 5.0 (using the 5.0a2
version) but we have a problem when retracting one unordered fact. The
fact is asserted from Java code in a way similar to other facts which
are retracted wiht success. Even other facts with similar type to the
problematic one are well retracted.
The exception error given when retrating the fact is similar to the
next:
Rete Exception in routine NodeNot2::RunTestsVaryLeft while executing
rule LHS: [NodeNot2 ntests=1 [Test2Simple:
test=EQ;tokenIdx=1;leftIdx=4;rightIdx=11] ;usecount = 1] while executing
defrule "DeleteReceivedMessagesWhenGoalSuccess."
Message: Corrupted Negcnt (< 0) at line 0: .....
I know it is not enough information to solve our problem, but it is
complex to extract a little example from the complete architecture.
So, does anybody suffer the same problem retracting some unordered
facts?
Does anybody have any idea about what is happening?
Could someone explain us the meaning of the message error with more
datail?
Thanks in advance.
