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.

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
