I am trying to extend a text field using FLDTYPE_*.XML concept. I could get the field to work. Now I need to create a RenderPattern for this field. The field needs to display information from a different list. Specifically, it needs to get information from more than one row, concatenate and display the information. Is this possible in RenderPattern?
I had the same problem! Is there any official documentation about the possible contents of RenderPattern? I had a look at some undocumented examples, but couldn't make much sense of it.
