Calculation to check Container valid reference.

[rrrichie]

Currently I have a script which walks through container fields and I check on error 100 to see if the file referenced in the container field still exists. Any ideas on how to do this with a calculation?

If you check on IsEmpty or IsValid don't work, cause FM 6 puts a nice "Could not draw this file" picture in the container, so it isn't empty or valid.

If the referenced file is an fp5 and rel is a constant (1::1) relationship to the file, then Case( not rel::constant = 1, "This file does not exist." ) may work for you.
