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

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
