[rules-users] empty cell in excel makes the LHS missing in the rule
Hi, i am using drools 5.4.0 and currently facing a typical problem. when ever any cell for LHS in the spreadsheet is blank. when the rules is compiled using the spreadsheet, the LHS for the empty cell get completely missed. drools don't even consider it as a empty string. The only workaround i found is to fill all empty cell with N/A and then merging the cells, which looks like a patch work. Any other way thru with i can tell drools to treat empty cells as empty string? - Thanks...

Re: [rules-users] rule infinitely loops, appears to be depending on naming on variable
In my opinion to have a Java Bean (or a DRL type declaration that is exactly the same for what regards this issue) with more than 20 fields is a code smell and however something very hard to maintain. I must admit that I've been tempted to use an int as bitmask when I developed that feature, but in the end I decided to go with a long thinking that in this way I could be sure to cover everybody's needs. Evidently I was wrong. That said I will experiment developing a custom made BitSet to check if I can address this issue without paying a performance penalty. Indeed I wouldn't like to have a performance loss (together with an higher memory occupation) for something that I still consider an extreme edge case. So what I will do in the short term will be to just disable the property reactive feature for types with more than 64 fields and emit a compilation warning when this happens.

[rules-users] Hibernate query and .RDL file
Hi, I'm a new member of this forum, and a new user of Drools.I need to apply a rule to the result of a sql query, my persistence layer is managed by Hibernate.I read this article http://www.kijanowski.eu/index.php?site=articlesarticle=drools_hibernatelang=en I read this article. You took a lot of doubts and I think it can work all integrated with Spring IoC. I only have a problem and do not know how to solve. Taking as an example the query of this article, if I wanted to go to run-time, the age of the query parameter in the file. DRL as I do?Can anyone help me? -- View this message in context: http://drools.46999.n3.nabble.com/Hibernate-query-and-RDL-file-tp4020168.html Sent from the Drools: User forum mailing list archive at Nabble.com.___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] rule infinitely loops, appears to be depending on naming on variable
Btw JVM JIT won't unroll the loop. It can only do this when the same instance is used repeatedly in the same method. If the instance used in the method changes on each invocation, as ours does, it's not possible for JIT to unroll the loop.

Re: [rules-users] All the values from one list must be present in other
I have drilled into similar problem but its bit different... I have a CompanyTaxPayer CompanyTaxPayer has a CountryDetails Mapstring, CountryDetail CountryDetail has Branches MapString, Branch Branch has Employee MapEmployeeNo, EmployeeDetails if the EmployeeType is Direct employee then company has to pay tax on their behalf I have another list of registered taxpayers (individuals). I need to get the list of all the employees (EmployeeDetails have some personal details) for the CompanyTaxPayer who are not registered as individual taxpayers (also have personal details). what is the best way of achieving this? -- View this message in context: http://drools.46999.n3.nabble.com/All-the-values-from-one-list-must-be-present-in-other-tp4019276p4020170.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] rule infinitely loops, appears to be depending on naming on variable
The only danger is with generated code, where you don't have full control over the final number of attributes. I would assume that, in those cases, one should avoid @propertyReactive altogether if there is a danger of exceeding the threshold? A warning would be ignored in an automatic developement process, potentially ending in loops where @pR is not kicking in as expected :( This is just for clarity, I do agree on the fact that huge bean classes should be used with care Davide -- View this message in context: http://drools.46999.n3.nabble.com/rule-infinitely-loops-appears-to-be-depending-on-naming-on-variable-tp4020158p4020172.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
