dear sir,
When I run the rules,it's error.I think it because that I used "and" and
"or" in the "not" conditional element.
One condition of rule which I wrote is " not
state_thresh(transitionid==411, stateid==283,ruleid==47, v_sta_evtthresh
:thresh, v_sta_cnt : count, customerid==v_customerid, srcaddress==v_srcaddress,
v_sta_threshtimefrom : timefrom ->(new
Integer(v_timestamp.intValue()+10).intValue()>=v_sta_threshtimefrom.intValue()),
v_sta_threshtimeto : timeto, v_sta_timeout1 : timeout
->((v_timestamp.intValue()<v_sta_timeout1.intValue())||((v_timestamp.intValue()<v_sta_threshtimeto.intValue())&&(v_sta_cnt.intValue()>=v_sta_evtthresh.intValue()))))"
When I delete this conditional element,it works.
What can i do?I want to add this fact only if the fact does not exist.
And there is some limit in this facts.
In the last email,i forgot to write the error tips.it is:
