I have a seemingly simple Test I wrote but when run it receives the error: Methods defined as TestMethod do not support getContent call. I do not have a .getContent call in my Test. I have narrowed down the error to most likely be the line "conid.add(con.Id);". I'm think the .add() when called acts like a .getContent()? Any thoughts on a way around the call?
Thank you,
Ryan
