Limit Number of Repeating Rows Based on Function

Hi,

although documentation says this should be possible (https://help.nintex.com/en-US/o365/#o365/O365Forms/FormControls/RepeatingSectionControl.htm%3FTocPath%3DWork%2520with%2520the%2520basics%7CActions%2520and%2520controls%7CControls%7C_____18) fast experiment proves that it doesn't.

Even a valid expression put in that setting is being replaced back with a default value.

What you can try is to create a rule, added to repeating section, that invalidates it if number of rows is bigger than expected, e.g.:

If(And(Is New Mode, count(FieldInRepeatingSection)>2), "Number of rows for new form cannot be higher than 2", If(And(Is Edit Mode,count(FieldInRepeatingSection)>1), "Number of rows for edit form cannot be higher than 1"))

Regards,
