Rule Updating a Property

[fundez]

Is it possible for a business rule to update a property other than the primary. We track a list of entry numbers by month. When a ser changes a date to a different month we need to update the entry number. We're doing this within a business rule since the entry number retrival is an async SQL call.

I see there is LoadProperty and also OutputPropertyValues, but I can't find examples of their usage.

Hi. You just have to provide the IPropertyInfo in the rules constructor and add it to the AffectedProperties. After that you can do context.AddOutValue(_yourProperty, newValue); to set the value from within a rule.
