> Hi,
> Sometimes I need to be able to put a +default 'TRUE'+ value for conditional columns that don't make any sense to have a 'FALSE' value.
> I give you the following case:
> When I want to update a fact A in the action part based on the value of a fact B on the condition part, it obviously makes sense to have an additional condition that fact A exists.
> But this results (as seen in the example screenshot below) in the option to flag the column that fact A exists TRUE/FALSE with a 'default' on FALSE.
> When you leave it FALSE, you get a compile error because the resulting rule code excludes the line, when you flag it TRUE, the line is shown ok and you don't get any errors.
> So the only real value that is possible is TRUE and it must be flagged TRUE for each row in the decision table.
> It is really hard for me to explain this to business users, when I give them the option to uncheck the column.
> Workaround/solution would be to allow a default value 'TRUE' and actually hide the column.
> Because for the business person, he doesn't care. 
> And the pity is that there actually is an option to add default values but only for literal equals...
> More generally this is a need to add some rule text that is always in the generated resulting rule code in the LHS or RHS rule part for all rows in the decision table.
> kr,
> Werner
