Drools beginner - unable to resolve method using strict-mode
by Stefan Schuster
Hi,
I'm new to drools, and I made my first steps using the very nice
video-tutorial "Build Pong in 13 minutes using JBoss Drools" found here:
http://www.youtube.com/watch?v=Omj4PR3v-nI
Eclipse shows building errors, but Pong start anyway. What does this error
mean?
in move.drl there is following rule:
*<rule "Move Bat Up" timer(expr: bat.speed, bat.speed) no-loop when*
* ui : PongUI( ready == true )*
* ( KeyPressed( keyText == "A" ) and bat : Bat( playerId ==
PlayerId.PlayerOne, y > pconf.padding + pconf.sideLineWidth )*
* or*
* KeyPressed( keyText == "K" ) and bat : Bat( playerId ==
PlayerId.PlayerTwo, y > pconf.padding + pconf.sideLineWidth ) ) *
* td : TableDirty( ) *
*then *
* tableG = ui.getTablePanel().getTableG();*
* tableG.setColor( Color.BLACK ); // background*
* tableG.fillRect( bat.x, bat.y, bat.width, bat.height );*
* *
* modify( bat ) { y = bat.y - 2 };*
* tableG.setColor( Color.WHITE ); // background*
* tableG.fillRect( bat.x, bat.y, bat.width, bat.height ); *
* modify( td ) { dirty = true };*
*end*
the error message is:
[Error: unable to resolve method using strict-mode:
org.drools.spi.KnowledgeHelper.td<http://org.drools.spi.knowledgehelper.td/>
()]
[Near : {... @Modify with( td ) { dirty = true }; ....}]
in another File (ui.drl) TableDirty is defined:
*declare TableDirty*
* @propertyReactive*
* dirty : boolean*
*end*
Any ideas what this error message means? And why can I start pong despite
this error?
Thanks a lot for helping me
Stefan

conways game of life
by Mark Proctor
For anyone looking for a good and complex example on how to write rules
properly, please look at Conways Game of Life in drools-examples, for
extra bonus points compare it to the old version in M1. You'll see
nearly all the logic is moved from java to the drl and we have removed
the need for nested objects by using objects relaitionally, which also
allows us to exploit cross products to drive the application.

KIE Scanner - 6.1.0.Final - not Loading LATEST kJAR
by Zahid Ahmed
Hi,
I am working on Drools 6.1.0.Final.
And my LATEST assets are not getting loaded using KIE-SCANNER. We have created a kJar 1.0 with 5 rules in KIE-Workbench 6.1.0.Final. We start our application server with KContainer having ReleaseId(gtoup, Artifact , LATEST). Rules are firing. Now add another rule in workbench increment the kJar version 1.1 and perform build and deploy. After waiting for 5mins fire the rules in application, LATEST Version IS NOT downloaded in m2 local repo and old rules are getting fired. I even tries with setting maven's update policy as interval:1, but in vain.
KIE Scanner is only getting triggered if I manually change the latest version and last updated in metadata.xml in local m2 repo. In this case KIE Scanner loads the new rules.
Kindly let us know what needs to be done.
