Re: FileMaker/AppleScript interactions: Get(LastError)

Tim;

This is certainly a solution, although it's not perfect for two reasons. One is that you need to have specific field names known to both the script and to the FileMaker application (which is not robust because you have to remember never to change the names of the fields, or you have to pass the name of the field to the AppleScript.

But the bigger problem is that to capture all errors basically means putting a "try/end try" bracket around your entire applescript application, which makes it difficult to debug, because when an error occurs you have no clue where in the applescript it happened, which means that every time you debug the script you have to remember to comment out the try/on error/end try so that you can see where the error is.

Of course, when FileMaker captures the error the same thing applies, but when that happens I just take the AppleScript string (I always execute AppleScript from a FileMaker global so that I know exactly what code was generated if it failes) and plug it into an AppleScript editor and run it to find out exactly where the error is.

Is there any reasonable way to capture an AppleScript error via a FileMaker script?

I'd trap the error in the AppleScript and pass the result back to FileMaker via a global field. For example:

try
  -- AppleScript that may produce an error
on error msg number num
  set cell "Result" of table "Sys" to "ERROR " & num & ": " & msg
end try

(this uses FM7 terminology and assumes "Result" is a global field).
