Hi,
We demonstrated as number of different things in the last Monthly Modeling Highlight including:
- How Validation Rules can work together and lead to mandatory Fields
- How mandatory Fields can habe a Star in their Label*
- How Partial Validation works and when Error Messages can be shown.
Whilst demonstrating how Partial Validation works, I said something that wasn’t 100% true and I want to correct myself.
I was showing you how a Computed Helper Field can be used in Partial Validation to ensure that an Error Message is shown. I showed you that we can either:
- set this field to be Global or
- add this Computed Helper Field to the Screen where the Partial Validation is taking place
to ensure that the Computed Helper Field is Relevant for the Partial Validation. I also said that the Field Label* has a Star. This wasn’t true based on the models that I demonstrated but is possible.
A Star is added to the Label as we model a Mandatory Group in Rule 1:
NoGroupFilled(../Repeatable*)
and then reference this Mandatory group in Rule 2:
FieldNotFilled(Field) And AtLeastOneGroupFilled(Repeatable*)
When adapting the Rules to reference the Computed Helper Field, you need to reference the Mandatory Group so that the Field Label* gets a Star and also the Helper Field so that the Rule can be triggered by Partial Validation. This means that Rule 4 in the Models and Explanation should be:
FieldNotFilled(Field) And (FieldFilled(HelperField) Or AtLeastOneGroupFilled(../Repeatable*))
I hope you enjoyed the Monthly Modeling Highlight and we’ll see you again next month.
Happy Modeling
