Hi. I am working on Drools 5.5.0.Final and have a question regarding XLS and a Decision Table structure, I have a ConditionObject and an ActionObject and wanted to know or see an example for XLS that produces a "does exist" for the ActionObject in the when. I can simply write the rule in a DRL, but translating how to make the XLS compiler create the same is proving challenging. An example: I want to produce a set of rules like below rule "Test rule_11" when $c : ConditionObject( somefield ) EmbeddedObject(myField == AnEnum.SomeValue) from $c.embedded $a : ActionObject( ) then $a.someMethod("value") $a.someMethod2(10) $a.someMethod3("A") end rule "Test rule_12" // some other AnEnum checks. What I can't work out is how I get the test of "existence" of the Action Object into the "when" for the rule, so that I can "use" the Object in the ACTION. In addition, is there a away that I can avoid needing a whole column just for "existence of an object with a field.. collect as a variable $c : (ConditionObject( somefield )" ? CONDITION CONDITION ACTION ACTION ACTION $c : ConditionObject EmbeddedObject() from $c.embedded $param myField == AnEnum.$param $a.someMethod("$param") $a.someMethod2($param) $a.someMethod3($param) "Description" "Description" "Description" "Description" "Description" somefield SomeValue value 10 A somefield SomeOtherValue someOtherValue 50 B This is the XLS of the above. https://www.dropbox.com/s/lw3zb5hwtjdbpcm/sample_rules.xls?v=1scns When this sheet is compiled, I get the following: How do I setup a "condition" for ActionObject to get in the when ? package packageName; //generated from Decision Table // rule values at A8, header at A3 rule "Test rule_8" when $c : ConditionObject(somefield) EmbeddedObject(myField == AnEnum.SomeValue) from $c.embedded then $a.someMethod("value") $a.someMethod2(10) $a.someMethod3(A) end // rule values at A9, header at A3 rule "Test rule_9" when $c : ConditionObject(somefield) EmbeddedObject(myField == AnEnum.SomeOtherValue) from $c.embedded then $a.someMethod("someOtherValue") $a.someMethod2(50) $a.someMethod3(B) end Ramon Buckland ramon(a)thebuckland.com _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hi, Thanks for the response. That doesn't seem to be right - this is what is produced from the Compiler. // rule values at A9, header at A3 rule "Test rule_9" when $c : ConditionObject(somefield) $a : ActionObject(this != null == "X") EmbeddedObject(myField == AnEnum.SomeOtherValue) from $c.embedded then ActionObject.someMethod2(50); $a.someMethod("someOtherValue") $a.someMethod3(B) end Is there a way to have a "when" rule produced where the data table row, for that CONDITION is empty ? The hack version I can work out is > CONDITION > $a : ActionObject > $param != null > this > this Ramon Buckland ramon(a)thebuckland.com On 22 May 2013, at 10:33, Michael Anstis <michael.anstis(a)gmail.com&gt; wrote: > Add an additional CONDITION for ActionObject. > > You'll need to probably add a constraint for "this != null" and put an X in the rows; e.g. > > CONDITION > $a : ActionObject > this != null > X > X > > > > > On 22 May 2013 09:55, Ramon Buckland <ramon(a)thebuckland.com&gt; wrote: > Hi. > > I am working on Drools 5.5.0.Final and have a question regarding XLS and a Decision Table structure, > > I have a ConditionObject and an ActionObject and wanted to know or see an example for XLS that produces a "does exist" for the ActionObject > in the when. > > I can simply write the rule in a DRL, but translating how to make the XLS compiler create the same is proving challenging. > > An example: > > I want to produce a set of rules like below > > rule "Test rule_11" > when > $c : ConditionObject( somefield ) > EmbeddedObject(myField == AnEnum.SomeValue) from $c.embedded > $a : ActionObject( ) > then > $a.someMethod("value") > $a.someMethod2(10) > $a.someMethod3("A") > end > > rule "Test rule_12" > // some other AnEnum checks. > > What I can't work out is how I get the test of "existence" of the Action Object into the "when" for the rule, so that I can "use" the Object in the ACTION. > In addition, is there a away that I can avoid needing a whole column just for "existence of an object with a field.. collect as a variable $c : (ConditionObject( somefield )" ? > > CONDITION CONDITION ACTION ACTION ACTION > $c : ConditionObject EmbeddedObject() from $c.embedded > $param myField == AnEnum.$param $a.someMethod("$param") $a.someMethod2($param) $a.someMethod3($param) > "Description" "Description" "Description" "Description" "Description" > somefield SomeValue value 10 A > somefield SomeOtherValue someOtherValue 50 B > > This is the XLS of the above. > > https://www.dropbox.com/s/lw3zb5hwtjdbpcm/sample_rules.xls?v=1scns > > When this sheet is compiled, I get the following: How do I setup a "condition" for ActionObject to get in the when ? > > package packageName; > //generated from Decision Table > // rule values at A8, header at A3 > rule "Test rule_8" > when > $c : ConditionObject(somefield) > EmbeddedObject(myField == AnEnum.SomeValue) from $c.embedded > then > $a.someMethod("value") > $a.someMethod2(10) > $a.someMethod3(A) > end > > // rule values at A9, header at A3 > rule "Test rule_9" > when > $c : ConditionObject(somefield) > EmbeddedObject(myField == AnEnum.SomeOtherValue) from $c.embedded > then > $a.someMethod("someOtherValue") > $a.someMethod2(50) > $a.someMethod3(B) > end > > > > > Ramon Buckland > ramon(a)thebuckland.com > > > > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users
