Issue

In this scenario you have a form that had empty columns that you'd use as an undefined column, and would appear blank in runtime (in K2 4.7). However,  after upgrading to K2 Five you see in runtime that the column is now showing the text "undefined."

Symptoms

This only occurs after upgrading from 4.7. to K2 Five.

Troubleshooting Steps

This is a behavioural change within K2 Five as the column will not appear at all if set to be empty in design time.

For this to work as expected, it will be best to insert a data label and remove the data label text from the properties section from the bottom right hand side of the Designer.

This should then show the empty column along with the other columns within Designer. ALM would not cater for this as this is not an issue on the form/views here.
