Drools compare two objects in decision table

Question

I have the following code in DRL file

rule "MyExample"
when
    $eentity : ExampleEntity()
    $sentity : SecondEntity( secondField == $eentity.getMainField())
then
    System.out.println(true);

end

This is works but I need to convert it to spreadsheet table. I tried so much variants but no one works. How can I write this rule in decision table?

Answer 1

Use a single condition column:

CONDITION
ExampleEntity($mf: mainField) SecondEntity
secondField == $mf /*param*/
Combine Ex with Sec on equal field values
x

The /*param*/ and the x is a hack to get the condition being generated for the row.
