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

I've seen Eclipse staying out of sync with actual DRL errors. Try
editing something harmless in move.drl, to force an update.

Thanks a lot for this hint, but unfortunately this wasn't the problem.
Any other ideas?
Thanks in advance

New subject: Drools beginner - unable to resolve method using strict-mode
I am not that drools eclipse plugin is able to see DRL types if they are defined in a
separate DRL file.
But if your app works well, it is only that.
If the type is really missing, you should encounter errors at runtime (when feeding the
knowledge base)

That rule style requires
dialect "mvel"
to be declared either at the rule level or globally in the DRL file,
do you have that?

yes, the dialect is declared as mvel. The pong game is also part of the
standard-examples that come with drools-experts. It's the same if I import
this example unmodified. But as it runs, it seams to be only an issue with
the eclipse plugin. Annoying, but no serious problem.
thanks to all for your help!

Define the type as a java class and the error should go away .
