This is peculiar. I created a minimal example for the purpose of responding to
your request using just the document-based application template. I added
public.plain-text as a document type in my application's properties and a
single line of code to MyDocument.rb:
def readFromData(data, ofType:type, error:outError)
puts "readFromData"
outError.assign(NSError.errorWithDomain(NSOSStatusErrorDomain,
code:-4, userInfo:nil))
nil
end
Based on what was happening in my original attempt, when I did File > Open, I
didn't expect to see "readFromData" on the terminal. But there it was. So
something I did in my original app must have screwed this up. The thing is, I
have no idea what. I did delete the readFromData method because I intended to
use readFromURL instead, but then I ended up deciding to go with readFromData
after all and reinstated it. I guess I'll just start over with a new template
and see if the problem occurs again.
Thanks,
Mike
