Validating Files

Brittany

Hi all,
I have an issue where i want to automatically add file when another one is submitted. But if the file is not there, then it should move on. Currently i have this implemented as a preprocessor where i just use addFile() but if the file is not there it throws an error where it can't recover from even though i do have it encased in a try-catch. Is there a way to either accept the error and move on or check to see if the file is there before trying to add it to the workflow?

Thanks
