Re: [rules-users] Issue using global 'variable' with Drools 5.2 in DRL
Hi Wolfgang, Thank you for answering, here is the rule rewritten but closer to reality: // package // imports global java.util.Date now; rule MyRule salience 5 when // Prevent rule activation for other offer types. MyObject(type == Type.TYPE_SOUGHT) $candidate : Candidate( subObject.dateField != null subObject.dateField.time = now.time) then // do something end A value for 'now' being set like so: session.setGlobal(now, new Date()); // Date being the java.util.Date. But I do not think that matters because 'compilation' fails at this point.

Re: [rules-users] Issue using global 'variable' with Drools 5.2 in DRL
If it a java.util.Date then drools supports comparing them out of the box so you can just do subObjcet.dateField = now. Just make sure you don't mix up instances of java.util.Date and java.sql.Timestamp (eg if you have jpa code fetching object from the db) as sun in their wisdom made it that you can't compare them with each other!

Re: [rules-users] Issue using global 'variable' with Drools 5.2 in DRL
Please follow Thomas' advice. That now.time worked in 5.1.1 was actually an accident, as it contradicted the specs. I'm not sure whether this behaviour is going to be reinstated. If you do need to do the comparison on long (milliseconds since the epoch) values you'd have to do subObject.dateField.time = (now.getTime()) which works in 5.1.1, 5.2.0 and 5.3.0.so.far. (Being able to omit the parentheses was promised for 5.2.0; hopefully we'll have it in 5.3.0.) -W On 23 September 2011 14:54, Slorg1 slo...@percipiomedia.com wrote: Hi Wolfgang, Thank you for answering, here is the rule rewritten but closer to reality: // package // imports global java.util.Date now; rule MyRule salience 5 when // Prevent rule activation for other offer types.

[rules-users] Issue using global 'variable' with Drools 5.2 in DRL
Good evening, I am porting our project from Drools 5.1 to Drools 5.2 and I am running into a couple of issues. Most I solved except: It seems that our global variable is being completely ignored. I have declared the following after package imports : global java.util.Date now; When calling it in a rule: rule MyRule when EXPRESSION = now.time then // things to do end Then I get the following error at 'compile' time : Not possible to directly access the property 'time' of declaration 'now' since it is not a pattern I do not know what to make of it. I have tried to change it to now.getTime() without success. Thank you in advance for your help. -- View this message in context: http://drools.46999.n3.nabble.com/Issue-using-global-variable-with-Drools-5-2-in-DRL-tp3360343p3360343.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

As it is written it can't be correct, global or no global. -W ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
