FieldRule in Table - Acces to items in Form

Is there a way to create a rule on a table-field/item with a condition to a certain field/item in the form?

I think this is intentionally not possible. How it should work for each row, how would the rule iterate across all rows and some resolve the composite result?

Perhaps you can somehow hack it via JavaSript - try to use table item events to manipulate "global" items.

It would be the other way around:

Example:

Form: F_CustomerIDRequired: yes/no

Table-Entry: if F_CusterIDRequired == yes then TblCusterID is required. So no loop over the table.

Yeah, some hacking via JS could solve this, but I try to avoid to intense JS in Domino Leap (if possible)
