Do you mean you cannot insert NameValue facts into working memory? If this is the case, then you might have to use eval or MVEL dialect. Based upon your model below I assumed you could insert NameValues:- LineItem-->getParameters() returns Parameter[]
Parameter->getNameValueArray() return NameValue[] Each NameValue has name and value attribute _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bhattacharya, Sougata Sent: 03 October 2007 13:23 To: Rules Users List Subject: RE: [rules-users] Arrays help Yes that's the simple one, but I can't send the NameValue, I will send only the LineItem _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Anstis, Michael (M.)

Now I have LineItem object in working memory, how to test the value of each value of NameValue object. LineItem-->getParameters() returns Parameter[] Parameter->getNameValueArray() return NameValue[] Each NameValue has name and value attribute Any help?
