How to define dynamic CONDITION in guided decision tables using drools workbench

[hareesh kumar]

Hi all,

I am using drools work bench 6.4.0 Final.

is it possible to create rules with extended decision tables like below:

CONDITION        ACTION

age                    type

--------------------------------------

<18                    minor

>18                    major

>60                    senior

Cureently am doing like below:

CONDITION     CONDITION     ACTION

age >                   age<             type

-----------------------------------------------------------

18                                             major

60                                             senior

                            18                 minor

Can anyone please help me??

If you define a column and pick "(no operator)" in the drop-down you can specify the operator in the cell.

You however loose any data-type validation (the cell effectively becomes a Textbox) so you can enter, for example, "> banana" for a numerical field.

Here is my Data Object:

package test.testing;

/**

 * This class was automatically generated by the data modeler tool.

 */

public class PersonDetails implements java.io.Serializable

{

   static final long serialVersionUID = 1L;

   @org.kie.api.definition.type.Label(value = "Age")

   private java.lang.Integer age;

   @org.kie.api.definition.type.Label(value = "Name")

   private java.lang.String name;

   public PersonDetails()

   {

   }

   public java.lang.Integer getAge()

   {

      return this.age;

   }

   public void setAge(java.lang.Integer age)

   {

      this.age = age;

   }

   public java.lang.String getName()

   {

      return this.name;

   }

   public void setName(java.lang.String name)

   {

      this.name = name;

   }

   public PersonDetails(java.lang.Integer age, java.lang.String name)

   {

      this.age = age;

      this.name = name;

   }

}

Attached column definition, action definition and decision table.

Here is Rule source:

package test.testing;

//from row number: 1

rule "Row 1 testGuidedTable"

dialect "mvel"

when

ageValidation : PersonDetails( )

then

modify( ageValidation ) {

setName( " Minor" )

}

end

You need to click on the "operator drop-down" and select "(no operator)".

Yes @Michael.. i have selected that only :)

It is showing as "please select an operator" even after selecting (no operator) option for me.

Note: 1.  If i do not select anything from dropdown, it is asking me to select operator

2. If i select (no operator) then it is accepting but showing as "please select an operator"

Do i need to do any settings??

Hmm. Ok to be honest I tried 7.0.0-SNAPSHOT... can you try the same? If I get a chance I'll try 6.4 (but if it's a bug it won't be fixed until 7.x)

Hi Hareesh, did you find any solution for this? I have the same problem with object Map, only can select "equal to", "null" ...etc., but I want select minor or major...
