Re: [rules-users] JBRULES-3260: Events forced to zero expirationOffset
Hi Robert, Good catch. I fixed this and will commit it in a few minutes. It will be included in the next release. You will be able to download fixed binaries from hudson or you can build them yourself.

Re: [rules-users] check if a Enum object is present in condition
Hi, Ansgar,
Thanks for your prompt response :) I was actually referring to enum
literals. Now it works!
Thanks,

[rules-users] JBRULES-3260: Events forced to zero expirationOffset
It seems like ever since I found this, I can't stop tripping this condition. Basically, while adding the DRL files to the KnowledgeBuilder, ReteooRuleBase decides it has to reconcile event definitions from different "packages", so it looks for any that are assignable. At first I thought this was just a guard against having a parent expire quicker than a child class and breaking rules for the child. But now I'm getting this condition for A SINGLE CLASS WITH NO INHERITANCE. At the root of the problem is ReteooRuleBase line 477: node.setExpirationOffset( Math.max( node.getExpirationOffset(), typeDeclaration.getExpirationOffset()+1 ) ); Since neither node nor typeDeclaration have declared expirations, they both have expirationOffset values of -1. The code evaluates: max(-1, -1 + 1) sets the expirationOffset for node to zero, and from then on my objects are expired literally as I insert them. If someone could more clearly state the conditions that trip this code, I'd do my best to avoid them. I've already eliminated inheritance among my events, but that doesn't seem to be enough. -- View this message in context: http://drools.46999.n3.nabble.com/JBRULES-3260-Events-forced-to-zero-expirationOffset-tp3444069p3444069.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

Is it actually a property of an enum or rather one of the enum literals?
If it is actually a property, you will need to obtain an instance of the
FrontendScreen enum first. If PLAYGROUND is actually an enum literal and you
want to bind this literal to a variable, use:
$screen: FrontendScreen( this == FrontendScreen.PLAYGROUND )

Re: [rules-users] Define global variables at the top of a rules file
There is no way the truth of true can be changed and, by definition, when there is no change in the condition there is no chance for another firing of the rule.

[rules-users] check if a Enum object is present in condition
Hello,
I try to put a condition in my LHS, such as:
rule "initial_playground_dialog"
#agenda-group "firstTimeUser"
#salience 99
when
$gst :
GameStateController(!hasEventOccurred("initial_playground_dialog"))
$list : List()
$screen : FrontendScreen.PLAYGROUND
then
end
where 'FrontendScreen' is an enum and PLAYGROUND is its property. However I
get a syntax error. What's the proper way to check for and assign such a
session object?
Any help is appreciated!
Best regards,
Martin

Re: [rules-users] Define global variables at the top of a rules file
Hello, Thanks for your response! But I don't understand why such a rule with a high salience which looks like: global int VARIABLE; rule "init" salience 999; when (eval(true)) then VARIABLE = 1; end would fire only once?
