Using the New Responsive Designer in Nintex for Office 365, I need to create a submit rule that will check if "Max Age" is greater than "Min Age" for each row in a repeating section (and throw a validation error if not). I am able to create this rule in the old responsive designer (see "nintex-old-responsive-designer.jpg") but I cannot seem to set the rule up in the new responsive designer as the closest I can get is to select the "minAge" via the form tab in the formula selector, but the dialog implies that this returns the entire array of values rather than the value of the field in the current row (see "nintex-new-responsive-designer-rules.jpg") and hence complains that the "formula return type does not match type 'number').
Out of curiosity, I checked the new repeating section control in NWC and found that it has implemented a "current row" selector in the forms controls (see "nwc-currentrow-selector.jpg") and that makes the rule work as expected (see "nwc-validation.jpg").
So my question is whether my finding is correct that there is no current way to implement a row level validation check on fields in a repeating section with the New Responsive Designer in Nintex for Office 365? Or am I missing something terribly obvious as I can't believe this requirement hasn't already come up.
Secondly, if that is the case then can we expect the "current row" selector currently implemented in NWC to come to Forms for Office 365?
