I'm using a DSL with my DRL file and I've read through the documentation but I've gotten hung-up on the syntax. Below is a rule from my DRL and the expansion in my DSL. My rule in the DRL: *rule* "Maximum Order Amount Exceeded" *salience* 9800 *when* There *is* an Order *with* - an amount that exceeds 100000 *then* Manually release the Order *end* My DSL: [condition][]There is an Order with=Order() [condition][]- an amount that exceeds {number}=amount >= {number} [consequence][]Manually release the Order=setManualRelease(drools.getRule ().getName()); What I would like to do is add to my consequence the following in red: [consequence][]Manually release the Order=setManualRelease(drools.getRule ().getName());*retract(theOrder);* I know that I would need to modify my condition statement to be able to use the variable *theOrder* in my call to retract: [condition][]There is an Order with=*theOrder *: Order() but is there a cleaner way to achieve this? _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

I was just looking for a more "short hand" syntax, one where I would not need to declare *"theOrder".* On the same subject though, I compiled my rules with the DRL/DSL editors in Eclipse (very nice by the way) and I am getting a compilation error being caused by my DSL entry: [consequence][]Manually release the Order=setManualRelease(drools.getRule ().getName());*retract(theOrder);* It seems that there is an issue with the *retract(theOrder);*statement. *The method retract(Order) is undefined for the type Rule_Maximum_Order_Amount_Exceeded_0 * Might you have any idea as to why this would be occurring or exactly what the message is meaning?

I did make certain that my rule file had the extension of .dslr. I discovered this early on and realized the importance when I renamed it. Of course I renamed it back to .dslr once I saw the difference. The DRL preview of my rule is as follows: *rule* "Maximum Order Amount Exceeded" *salience* 9800 *when* theOrder : Order( amount >= 100000 ) *then* theOrder.setManualRelease(drools.getRule().getName());*retract*(theOrder); *end* Thanks once again for all the help... *"Edson Tirelli" <tirelli(a)post.com&gt;* Sent by: rules-users-bounces(a)lists.jboss.org 09/13/2007 04:39 AM Please respond to Rules Users List <rules-users(a)lists.jboss.org&gt; To "Rules Users List" <rules-users(a)lists.jboss.org&gt; cc Subject Re: [rules-users] Assistance with DSL syntax No, you need to identify which object are you trying to retract, since you may have multiple facts constrained in the LHS. Regarding your problem, make sure your rules file has the extension ".dslr" so that eclipse selects the correct editor when opening the file. Then click in the DRL preview in the editor bottom tab. Can you please show me the result of the DRL preview?
