I have an application that uses response documents to store additional information.
When the document is saved I need it to catch up with a couple of fields in the parent document.
Sticking this code into the computed Name field sorts this out.
T:=@getdocfield($ref;"name");
@if(
@iserror(t) & name=""; @return("Parent not found");
@iserror(t); @return(name);
T)
It also works when creating the document.
