Re: [rules-dev] Cast-away bug


> Explanation?

   It was a feature to check if anyone would try that... ;)

https://issues.jboss.org/browse/JBRULES-3193

   Feature removed...

   Thanks for reporting, let me know if you still see any problem.

This rule

rule "test"
when
    $l : ArrayList() from collect (MyClass (attribute == false));
then
    for(Object o : new ArrayList( $l )) {
        MyClass o2 = (MyClass) o;
        modify(o2) { setAttribute(true) }
    }
end

does not compile:  The method setAttribute(boolean) is undefined for the type Object

This, however, works:
   modify( (MyClass)o) { setAttribute(true) }

Explanation?

[rules-dev] A dotty bug

Consider these six variations of a pattern constraint:

   $a: Student( $someStudent.name != null  )
   $b: Student( $someStudent .name != null  )
   $c: Student( $someStudent. name != null  )
   $d: Student( $someStudent.getName() != null  )
   $e: Student( $someStudent .getName() != null  )
   $f: Student( $someStudent. getName() != null  )

Where is the bug - surely a space next to a separator can't do any harm? But indeed - $c is flagged with a not very helpful error message: "Unable to build constraint as  ' name' is invalid".

Now, what about $d, $e and $f? Is it also $f,  b with the space after the dot, which is flagged?

Surprise, surprise: here it is $e that's pilloried with a lot of gobbledegook (note the invented "method" $someStudent):

Unable to Analyse Expression $someStudent .getName() != null:
[Error: unable to resolve method using strict-mode: add2map.Student.$someStudent()]
[Near : {... $someStudent .getName() != nul ....}]

More fun of this kind is to be had from similar expressions on the RHS, especially when dialect "mvel" is set.

Cheers
Wolfgang

Let me confirm that a rewritten schema using

    * two cardinality changes 'maxOccurs="unbounded"'

    * removal of the extension constructs for all AND and OR connectives,
      replacing this by "xs:choice" constructs.

    * insertion of the relevant "and-*-*" and "or-*-*" in the relevant
      type used for abstraction, thus eliminating later extension

does lead to a schema that validates also the above four rule files.
I am using "xmllint-2.7.8" to perform validation, working in the firm
belief that not only Java specific tools be the sole instruments
of choice.

Who is the author of the official XML Schema "drools-5.2.xsd"?
Clearly I need to discuss matters with him or her.

Best regards,
  Mats Erik Andersson

[rules-dev] JIRAs JBRULES-3195, 3196, 3197, 3198

Without much hope of getting fixes (althoufh an infinite loop *is* rather nasty) I have created 4 more JIRAs, most if not all of which are related to MVEL. However, I feel compelled to document the oddities exhibited by MVEL, especially where it does not accept or handle code that works well or is decently diagnosed when using Java.

https://issues.jboss.org/browse/JBRULES-3198 is particularly remarkable as it seems to indicate that MVEL deviates from Java even at the lexical level, processing something like   X/*Y*/    as a (class) name.

Cheers
Wolfgang

[rules-dev] sheriff patrol: droolsjbpm-integration: failing tests

The following tests fail on both master and 5.2.x branch:-

  • org.drools.camel.component.XStreamBatchExecutionTest.testQuery [drools-camel]
  • org.drools.runtime.pipeline.impl.XStreamBatchExecutionTest.testQuery [drools-pipeline]
They have been <at> Ignored on master for some time and I have ignored them on 5.2.x now too.

AFAIK, something in the land of "queries" has broken them. Since there has been a lot of change in this area for BC it might be best somebody else investigate the tests and provide a remedy.

Cheers,

Mike

[rules-dev] Rules Fest Last Minute Medical Meetup Speakers Wanted

Rules Fest is very close (24-28th of October, San Francisco) and this year RHT are sponsoring the bootcamps to a high level to ensure that they are made freely available to all.
http://rulesfest.org/html/home.html

Thu the 27th will follow the normal intro format as previous years, along with time to ask questions of core developers.

At the last minute budget was found for an additional day on Friday the 28th. Due to the success of the healthcare meet up in San Diego 2010, we would like to try and dedicate this day to healthcare.

We would like this day to be 100% community presented, by real practitioners. If you are doing anything interested in the area of healthcare related to rules, workflow, events, ontologies, distributed intelligent agents and would like to talk, please contact me asap: mproctor at codehaus d0t org.

The talks do not need to be Drools specific, but it should be relevant to any one looking to do Open Source based technology implementations of the previously mentioned areas. Applied, theoritcal and technical talks are all welcome.

Again sorry for the last minute notice, but hopefully we can still make this into a great community oriented day.

Mark

Drools Project Lead and Co-creator

Mark

I'm sure that LSE has some short courses for the general population on business planning - but then you would
have plan the time to take the course.  Buggers!  :-)

Hi Salaboy,

I've added the presentations to the relevant page - please have a look and check when you get a moment.

I hope to have a look at some of the presentations at some time...
