I am using Appian 7.2 and have an issue while using grids in forms. I am using the enumerator function to print the index of my array and store the indexes into a ac!variable.
I have set the index column as hidden, however I am not able to retrieve the value of the index(in custom output) while submitting. If I change the setting of the column from hidden to visible, it works fine. Is this a known issue or am I doing something wrong?...
