Re: [rules-users] Action Object and Condition Object in XLS DTABLE

CONDITION $a : ActionObject $param != null this this

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
