[rules-users] Planner with a list of planning variables
Hello all, can I use as planning variable a list of values? Here's a test use case: planning a food recipe, where the recipe can have say maximally 5 ingredients (taken from the solution property, I guess). So far I could find in the examples and documentation, it's all about ONE planning variable in the solution, but here I'd need a LIST of such... is it actually doable this way? I cannot do it the other way around, as an ingredient may be found in more recipes...

[rules-users] Starting Guvnor in Eclipse
Hi all, any Eclipse users around here? I have followed the instructions here: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/README.md for Eclipse Helios+EGit+m2eclipse. I downloaded 5.2.0.Final from https://github.com/droolsjbpm/guvnor.git, imported all Maven projects it could find in the directory (except guvnor-docs which misses something and I didn't care). The Guvnor application will start in development mode, but: - Firefox is causing often 100% CPU with it (might be the development mode) - Eclipse Development Mode view shows LOTS of errors like this: [ERROR] [org.drools.guvnor.Guvnor] - Errors in 'file:/C:/PocDev/GitHome/git/guvnor/droolsjbpm-ide-common/src/test/java/org/drools/ide/common/client/modeldriven/SuggestionCompletionEngineTest.java' [ERROR] [org.drools.guvnor.Guvnor] - Line 47: No source code is available for type org.drools.ide.common.server.rules.SuggestionCompletionLoader; did you forget to inherit a required module? [ERROR] [org.drools.guvnor.Guvnor] - Line 49: No source code is available for type java.util.jar.JarInputStream; did you forget to inherit a required module? Again, one can work also like this but seeing hundreds of errors is not helping at all when I try to tinker with something somewhere. Plus there's the 100% CPU thing... where and what should I inherit more than Maven is configured already to inherit? Tinkering around: - I set all other projects as dependencies - I set to export all sources from all projects (but there it bitches also about missing java.util sources, who cares about these?)... - added all these sources to the run configuration nothing changed, I still have the above errors from both system libraries AND project dependencies. Or do I experience the problem mentioned in this message? http://markmail.org/message/h52xvo4j52msambe#query:+page:1+mid:lg4mlgiof4giuiaq+state:results Thanks for any hints, JC ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Guvnor another few questions...
Hi all, I played a bit with 5.2.0.Final and I have a couple of more questions, I don't know whether I misread the documentation or I just expect too much... 1. Can I use functions in a web decision table columns? Because if yes, I just can't figure out how... Either way would be good, calling a function defined in Guvnor or calling a static function of some model class (like ModelClass.getMyParameter(...) ). Anything which would result to an eval() block... or should I use a "formula" caclulation type then enter in each cell the same eval(function()) call? Even so, I still need a rule like: rule"mine" when eval($var.myFunction($date.lastTime))... 2. I see discussions about translations of Guvnor GUI, and I see them mentioning a certain Constants.properties file. I can't see that file anywhere in my installation, nor any other language translation for that matter although French and Spanish were mentioned. Is there by chance a German translation around, and even if no, how can one generate and use one? 3. I have the feeling that uploading a new version of the POJO model jar updates the existing classes only. That is, if I remove a class from the Java model and upload it again, then package validation will fail because it doesn't find the old class (even when NOT used by any rule or anything I know of). Wasn't there somewhere a Guvnor dialog where one could remove POJO model classes by hand one by one? I kind of remember such a class list... 4. And is it really that way that uploading a new POJO model requires an application restart to actually use it? 5. If I upload something from Eclipse it lands under "Other assets, documentation" even if they are Java classes which I hoped would land under Model... is there anything I can do about that? A Java POJO model once uploaded is just a jar blob afterwards, not usable from Eclipse anymore... 6. The declarative model defined in Guvnor is not much usable in Eclipse either, comes as an unrecognized text file. I didn't try to edit it in Eclipse, the lack of integration in the application classes would bring nothing. Could the declarative model mapped somehow to some Java classes (or generate classes out of it)? 7. Clicking a Guvnor repository business rule file in Eclipse throws a WebDav error "not found", both for brl and gdsl files. Could it have to do with the fact that the package doesn't validate at the moment? 8. Clicking in Eclipse in the Guvnor perspective a freshly created rule flow (nothing uploaded yet) throws an exception as well... 9. If I have a model class with a field called aThing, it will have an accessor called getAThing(). Guvnor after POJO import will keep both capitals - thus in the field selection dropdowns I will have the field AThing... should this be my only problem.

[rules-users] Guvnor errors stay forever
Hi all, Here's a funny thing I experience: I declare a function and do the mistake of verifying it before editing anything, while it's still a template (so it has chevrons). The verify obviously fails - but with a HTTP error 500! Server crashed?? Indeed I can see in the console: at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:951) [:6.0.0.Final] at java.lang.Thread.run(Thread.java:619) [:1.6.0_12] Caused by: java.lang.RuntimeException: Verifier Errors: [ERR 102] Line 1:9 mismatched input '<' in function [ERR 102] Line 1:36 mismatched input '<' in function "calculateAge" [ERR 102] Line 1:46 mismatched input '>' in function "calculateAge" Parser returned a null Package I see quite a few JIRAs about incomplete exception handling - GUVNOR-741, GUVNOR-690, GUVNOR-536, should I add the above to any of them? Whatever, an error is an error, but here comes the real problem: After the above I come to realize that each analysis of a package keeps adding the results of the previous ones, so the Errors/Warnings list just grows and grows. An old error will always come again even though the item it refers to is not even existing anymore (so I cannot analyse/verify anything reliably). I renamed the above function, I edited it so it doesn't have the chevrons, its code can be validated fine, but nevertheless Guvnor keeps throwing the same error 500 and the JBoss console keeps complaining about the ld function calculateAge and its chevrons each time I verify or analyse. And it does that by repeating the message for each retry once more. Either the error list is not cleaned after the verify, or some artifacts live too long. Logout and relogon keeps the list, but restarting JBoss solves the problem. . I really have the feeling GUVNOR-1499 has the same underlying problem... For the record: I'm on 5.2.0.Final on JBoss 6, Java 6 on Windows XP.

Hi, > Are you talking about DroolsCompilerAntTask and DroolsVerifierAntTask > Ant tasks (that I discovered after having read you email)?

[rules-users] compiling performance dropped with 5.0.1 to 5.1.1 upgrade
Hi all, my set of rules (100 files, 20 rules/file) was taking 30 seconds to compile until yesterday. Now I upgraded DRools to 5.1.1 and it takes about 2 minutes to compile. I'm on Windows XP and cannot notice any memory or CPU bottlenecks. I'm using an Ant task to do it, and the timing is exactly the same whether I'm using the DRools Ant compiler task, or I define a compiler task of my own. I can see in my own compiler task that this particular line is spending a few seconds per DRL file: builder.add( res, ResourceType.DRL ); so the effective compilation is the culprit right? I tried also to merge all the DRL files and compile them all-at-once but this didn't change anything. Do you have any idea what might have changed between 5.0 and 5.1 or what I could do to have it like before?

Re: [rules-users] Unable to load dialect java from Ant task
Thanks a lot for the answer. The problem is exactly that one: how could I know what the dependencies for the DRools compiler are?! I thought this list would know :)) Anyway, I'll print out the Eclipse runtime classpath and compare them two to see what stands out. The Ant task is mentioned here and there in the documentation (albeit without examples) so I kinda thought more people are using it. An older thread of this same list talks about adding (only) the drools-ant to the classpath, which of course solves the ant task itself but none of its dependencies... I find it difficult to believe that the compiler depends on some Eclipse stuff, especially after I added ALL the jars existing in the Eclipse configuration. The only thing I cannot directly rule out is the classloader issue, but that's also the only thing I have no idea how to debug/solve :( Thank you, M --- On Sun, 9/21/08, Edson Tirelli <[EMAIL PROTECTED]> wrote: > This is always related to classpath problems.
