Re: [rules-users] Spreadsheet: Rule Compilation error (xxx) cannot be resolved: Keeping running total

I’ve no idea why I said xml rather than drl – still too early in the morning. It should be there in the documentation, you use $1 and $2 (etc). But in this case why do you want to it’s easier for people to insert the values into two separate columns. You want something like the following NAME CONDITION CONDITION f : Fact value > $param Value <= $param Rule Name Payment More than Payment max rule 1 1500 This also has the benefit you can add catchall rules for the top and bottom by leaving the appropriate column empty - eg payment <= 0, or payment > 20000 Thomas From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of john@oa Sent: 12 September 2011 11:12 To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] Spreadsheet: Rule Compilation error (xxx) cannot be resolved: Keeping running total Ah Okay, That kind of makes sense, although I can't seem to find any documentation on how to merge the condition column, i.e. to have to parameters in one column: Tried this to no avail (using the , as the implicit AND) Payment value > $param1, value <= $param2 Payment In Range 0, 1500 1500, 2000 2000, 3000 3000, 4000 4000, 5000 5000, 10000 10000, 15000 15000, 20000 20000 On Mon, Sep 12, 2011 at 8:21 AM, Swindells, Thomas [via Drools] <[hidden email]</user/SendEmail.jtp?type=node&node=3329292&i=0>> wrote: If you dump out the xml it converts the spreadsheet to you can see what the resulting DRL is. Mantis is right in what the output is – if you don’t merge the condition column you’ll get a drl as below (If there exists a Condition (c1) such that its payment > $param(1) AND there exists a Condition (c2) such that its payment <= $param(2). If you merge the condition column the constraints apply to the same Condition object with the comma being the implicit and (if there exists a Condition c1 such that its payment > $param(1) AND its payment <= $param(2).

Yes, I need the ranges to be mutually exclusive, what is the easiest way to do that? Feel a bit cheeky asking another question, but you seem to know what you are talking about! I have tried adding two conditions to enforce the range, but that doesn't seem to work - see below. I still get multiple rules firing. Also can you recommend any good resources for learning all of this, apart from the online documentation? Would you know if any of the Drools books are any good? payment > $param payment <= $param Payment Greater Than Payment Less Than or Equal To 0 0 1500 1500 2000 2000 3000 3000 4000 On Fri, Sep 9, 2011 at 2:22 PM, laune [via Drools] <[hidden email]<http://user/SendEmail.jtp?type=node&node=3323074&i=0>> wrote: The error you get is due to the second condition (application: Application()) not being included in the generated rules. Empty cell means: the column's snippet is not included in the rule. Since you don't have a constraint for Application() you can employ a trick: remove the column and prefix the text application: Application() to the text in cell C7. In Rule 1, do you really want to test whether a payment is not greater than zero? Do you realize that Rules 2 and 3 would both fire for certain payment amounts? You can update a String field. To concatenate, use x.setString( x.getString() + "whatever" ); -W On 9 September 2011 14:08, john@oa <[hidden email]<http://user/SendEmail.jtp?type=node&node=3322896&i=0>> wrote: Guvnor: guvnor-5.2.0.Final-tomcat-6.0 Hi I am a Drools Newbie and I have an integer field called score that I need to add to when a rule matches in a spreadsheet decision table. i.e. the score field should hold a running total of all scores that are matched. However, I can't even update the field in the table. I have attached the spreadsheet for review. In this spreadsheet I am simply trying to set the score, and that is failing with: DScoringTable] Rule Compilation error application cannot be resolved My goal is to have different decision tables that will all need to update the same score, and keep a running total of the total score. Any help very much appreciated! I hope that I am just missing something obvious. http://drools.46999.n3.nabble.com/file/n3322713/demo-score-sheet.xls demo-score-sheet.xls<http://drools.46999.n3.nabble.com/file/n3322713/d... In future I may wish to also update a String field and keep concatenating to that field, is this possible?
