[rules-users] could not access property ('=')

Hi. I've currently evaluating Drools 4.0 for a project of ours and I'm running into some problems. I have a rule which looks like this: rule W250.42 Editable when DTO(w250_4_1.value in (0,1,6,7,A,C,D,G,L,M,P,Q,S,V,Z) ) then System.out.println

Re: [rules-users] getGlobal

globals are automatically in injected you don't need the getGlobal at all from within a consequence. However if you are in java land you you may need to read a global value and we can't inject it there, so thats the reason for this. Mark hypnosat7 wrote: Hi, Is it important to use

Re: [rules-users] OR operator

using 'or' like that results in subrule generation, i.e. rules will fire for all matching combinatinos - this is not what people normally want. you can also do it using field constraints person : (Person (interests contains Golf || contains Soccer) Jaikiran Pai wrote: Hi, This is a very

yes you can use a variable, and no you cannot dynamically generate rules in an eval. Mark Arsalan S. Zaidi wrote: Hi. Two questions: 1. Is it possible to use a variable in a IN(...) ? E.g. when $someVar : SomeObj() (pqr in (abc, $someVar)) then ...

Re: [rules-users] expander mappings empty !

This is not Drools-related but rather a generic Java problem. You should read the Java API of the Reader class. A reader remembers the last position it used to read out data. So if you try to use the same reader twice, the second time it will be empty, as it will already be at the end of the

I need the mapping for a wizard. In fact if I execute the methode below before the addPackageFromDrl(drlReader, dslReader) I have problems. private DSLMapping generateDslMapping(Reader dslReader) { DSLMappingFile dslMappingFile = new DSLMappingFile();

Re: [rules-users] OR operator

Jaikiran, This is only supported in Drools 4. In 3.0.x, you will have to use either a predicate or do what you were doing, but note that as Mark mentioned, the OR CE will cause subrule generation, meaning the rule will fire twice if both conditions are true. []s Edson 2007/8/13,

Re: [rules-users] could not access property ('=')

This looks like an MVEL issue, since your expression is being converted into an MVEL predicate. May I ask you please to open a JIRA for that bug? Meanwhile, a workaround that shall work for you and may give you improved perf is to split your pattern into 2 patterns using the from keyword:

How about RuleFlows? If there is a work flow flavor to these groups of Rules then I think a Rule Flow could help. I don't know how the underlying implementation works but I think that you will not have the when parts of those Rules not active in the Flow be evaluated. On 8/13/07, Yuri [EMAIL
