Class A has one-to-many relationship with class B.

I have a semantic validation rule with an audit, which does something with all children and returns a boolean. Right now the target class of the rule is class B but I assume the audit expression is called for each instance of class B. But calling it just once would be enough in my case to find out the result for each instance of class B.

So, instead of having class B as the target of the validation rule, is it possible to have class A as the target and then display the result on every child? In this case a triangle on every class B instance if the expression returns false for that instance.

Hello,

Unfortunately it is not possible to mix the validation target and the validation result.
If the target is class A, the validation decorator will be displayed only on class A. You have to choice between writing a validation rule for class B with an audit expression starting from this context or a validation rule for class A.
