you did create a new column with a fieldname for example: viewlink
you did create only one renderOption with a name for example: renderViewLink
and you did create a chunk with name: renderViewLink
and you added this into the chunk?
<a href="[[~[[+id]]? &scheme=`full`]]" target="_blank">View</a>
and you got an empty column?
which getlist-processor is your grid calling?
