Re: [rules-users] accumulate vs collect

Hi List, I'm trying to count the number of objects I have in the Working Memory using accumulate, but I'm having a ClassCastException thrown at me. Using a variant with collect, everything work OK. Can someone shed some light on this issue? Is it related to https://jira.jboss.org/browse/JBRULES-2202 ? I'm using Drools.5.0.1 and the fact is a declared one, as follows: declare t_1  regRowId : String  versionId : String  c_7 : String  c_1 : String  c_2 : String  c_3 : String  c_4 : String  c_5 : String  c_6 : Double end trying with : v945 : Number ( doubleValue  >=  1 ) from accumulate ( p : t_1 (  c_6 >= 20100511 && c_7 == "5" ) , count(p) ) I'm getting a ClassCastException:t_1, while using : v945 : ArrayList ( size  >=  1 ) from collect ( t_1 (  c_6 >= 20100511 && c_7 == "5" )  ) works OK. The reason I'm preferring accumulate over collect, is that I'm not really interested in constructing an ArrayList of the matched facts (worries about memory consumption), all I want is how many of them are there. The actual rule I'm using (although I don't think it matters) for the accumulate variant, is: rule "r95944.6"        dialect "mvel"        when                gnId : GoodNumbers()                 LogicalValue : Trader( gnId.goodNo==goodNo  )                 v945 : Number ( doubleValue  >=  1 ) from accumulate ( p : t_1 (  c_6 >= 20100511 && c_7 == "5" ) , count(p) )        then                RaResultCode rrc = new RaResultCode();                  rrc.setResultRuleId("95944");                  rrc.setResultRuleVersionId("6");                  rrc.setResultColor("R");                  rrc.setResultRuleCode("01");                  rrc.setResultAction("1");                  rrc.setResultGoodNo(gnId.goodNo);                insertLogical(rrc); end Thank you for your time. -Stathis _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
