Hi Nicholas,
Thank you for your update.
If there parameters are dependant on each other, and one of them can accept a Null value, the other one should also handle the case where the first parameter is Null. Thus your solution to set the dependent parameters AllowNull to true is the right way to go.
Other approach I can suggest you is to handle the first parameter's Null value in the expression e.g.:
Multivalue parameters evaluate to array of objects, also to conform to the expected type of arguments we use the Array utility function.
