[rules-users] JBRULES-2796 - NullPointerException in FromNode.destroyCreatedHandles

Hello, I think I am getting the same/similar problem as described in JBRULES-2796. I am using Drools 5.1.1 with Expert and Flow, here is the stack trace: Caused by: java.lang.NullPointerException at org.drools.reteoo.FromNode.destroyCreatedHandles(FromNode.java:336) at org.dro

Re: [rules-users] SPREADSHEET DECISION TABLE: Can I use functions into CONDITIONS?

Hi Zeta, Just to confirm: You'll find that writing an Excel VBA macro will not work, as they are neither MVEL nor Java. How I've handled it is created a Helper class with public static methods. Then in the Import section at the top of the file, I link to the functions I use, prefixed with the

[rules-users] SPREADSHEET DECISION TABLE: Can I use functions into CONDITIONS?

HI!, I need to check if a given date is between two dates. So, I would like to call a function that calculates if the given date is between other two(specifically, between current date and current date plus some months, and the variable "months" changes dynamically). I tried to write a function(ins

[rules-users] addpackagefromdrl removed and multiple DSL functionality lost?

Several posts refer to a pre-5.0 addpackagefromdrl method that builds a rule file for an associated DSL file. This let multiple DRL files be associated to a specific DSL file for compilation. KnowledgeBuilder.add(...) lets you add multiple DRL and DSL files, but it seems as if the "expander" keyw

Re: [rules-users] Guvnor service to compile part of a package ?

Other than custom selectors, as you have already discovered, I don't believe there is anything that fits your description "out of the box". Those clever chaps at Plugtree often have something up their sleeves; perhaps they know of something? There have also been a lot of changes for 5.2 but I'm uns

[rules-users] Guvnor service to compile part of a package ?

Hi all, I am looking for a clever way to compile only parts of a Guvnor package according to some criteria on items (categories, metadata ...), but outside Guvnor if possible. The main idea starts by the fact that it is a little bit complex for a business user to manage packages and compilation

Re: [rules-users] Question on modeling facts

Stops would be in some ordered collection; the equals for AbstractList is efficient enogh; it does check sizes before iterating in parallel. Perhaps the 2 termini should be checked first (if there's a wide range of lines), then (as Wendy proposes) the day; then the stations. -W 2011/5/4 Wendy M

Re: [rules-users] Question on modeling facts

How many train stops are you talking about? If it is only a few it might not matter if you don't have the many trains. When you are writing your rule if you narrow down by matching schedule first and then comparing all the stops that might help. An alternative to comparing two collections in

Re: [rules-users] Fw: Regarding Drools - Expert and Fusion

I don't know of any such links. Fusion depends upon Expert so they must coexist if you are to use Fusion. Fusion is really the CEP aspect of Expert, I don't believe it possible to "install" Expert without Fusion's extensions. An event based system would be one where you need to make temporal dec

Re: [rules-users] Looping through a vector object in a rule

I assumed claimHistory is not related to Claim in your example, if it is however you can also do this:- when $c : Claim( $a : aField ) $ch : ClaimHistory( aField == $a ) from $c.claimHistory then ... end Or, assuming bidirectional references:- when $c : Claim( $a : aField ) $

Re: [rules-users] Using constant for salience instead of hardcoded values?

Salience can be defined using expressions - so have you tried it? If referencing a static constant (perhaps in a java class) doesn't work you could try a global, if that doesn't work try defining a function call which returns the desired value, if that doesn't work you could add an extra fact con

Re: [rules-users] Looping through a vector object in a rule

You'd be better off inserting the individual claim history objects:- when $c : Claim( $a : aField ) $ch : ClaimHistory( aField == $a ) then ... end IIRC you can achieve the same by inserting the Vector by providing another rule to expand it first:- Vector claimHistory = getClaimHisto

Re: [rules-users] Using constant for salience instead of hardcoded values?

One way to achieve this (with a little extra effort) would be to use a DSL where you define START etc. as keywords with an expansion to "salience 100" etc. -W On 4 May 2011 10:09, alebu wrote: > Hi all, > Is it possible to use a constant for salience instead of hardcoded > value? It have a sence

[rules-users] Using constant for salience instead of hardcoded values?

Hi all, Is it possible to use a constant for salience instead of hardcoded value? It have a sence when you have many rules and only several salience level. They maybe more descriptive like START, VALIDATION, etc and easier to maintain in the future. If it not possible right now, then maybe it worth
