Hi Michael,

Thanks for  your reply.

Leaving a cell empty results in the condition not being added to the rule at all. Which is fine, cause then you're more flexible in grouping rules with different conditions together in one decision table
I actually found a way yesterday, which seems to me more like a workaround. But it works:

| 1 | RuleTable calculateSmell              |
| 2 |    CONDITION    |     ACTION          |
| 3 |                 | cheese              |
| 4 | cheese:Cheese() | setSmell("$param"); |
| 5 | for every cheese| set smell to stinky |
| 6 | somevalue       | stinky              |

By declaring the variable not in the row right underneath below the CONDITION cell, but in the row where you normally declare the conditions ( i.e. second row underneath the condition row
AND putting in some random value in the cell, that holds the parameter value, you can generate the desired rule:

#From row number: 6
rule "calculateSmell_6"
        when
                cheese:Cheese()
        then
                cheese.setSmell("stinky");;
end

Leaving out the parameter value results in the when line being blank, so you gotta fill in something.
I can live with that, but it seems to me more like a workaround, so I would be kinda curious whether there is (or will be) an "official" way of achieving this
Best regards,
Martin

Onderwerp: Re: [rules-users] How to generate rules from decision tables whereLHS has no field constraints

you should be able to do that - just leave the constraint cells empty, or put some comment in them.

Hello,
Maybe I have overlooked something, but I couldn't find a way to generate a simple rule from an excel decision table, where the left hand side contains no field constraints?
i.e.
rule "do we have cheese"
WHEN
cheese: Cheese()
THEN
RHS
End
Is there a way to achieve this?
Thanks in advance,
Martin
