I want to create a decision table with some empty cells.

the auto-generated rule is like this.

rule "Row 1 some name"
enabled false
salience -99
no-loop true
dialect "mvel"
when
    $p : Model1( name == "string" )
    $output : Model2( model3Code== ( $a.code ), model1Code== ( $p.code) )
then
    $output.setSomeProperty( false );
end

In the above code, you see because of column3 is empty $a not generated, and the build of rules failed.

My problem is to know how I can check if a cell is empty or not and empty cells ignore from Model2 conditions.

Finally, I found a solution for this.

If in the Model2 condition select type of condition to predicate and use $param inside it, when the cell is empty that condition not added to rule anymore. Only conditions that it's `$param" parameters are set will be generated.
