a : A( modified == "false" ) ==> here "false" is a String
and a.setModified( true ); ==> here true is a boolean
 
from your use of modified, I presume that modified is of boolean type. If it is, you'd probably want to do something like
 

rule "Rule3"

      dialect "mvel"

      when

            a : A( modified == false )

      then

            a.setModified( true );

            update( a );

end

 

because, modified will never be equal to "false" in your file cause it"s a String

Objet : [rules-users] Error with executing rules

Hi guys,

 

I have few .drl rules and 1 .brl rule (which I converted into a .drl rule as guided by the documentation online)

All my rules get created and fired. But the converted .brl rule does not get executed only.

I am unable to understand why.

Anyway I can check how it is working??

I put in the most basic rule which should work:

The coverted .drl file looks like this:

rule "Rule3"

      dialect "mvel"

      when

            a : A( modified == "false" )

      then

            a.setModified( true );

            update( a );

end

 

// A being my fact with attribute modified set to false in the beginning.

 

The import statements are in a rule.package in the same folder.

 

Please help me. I do not understand why this rule doesn’t get executed. All others do!

 

Thanks

M
