As you mentioned, had been working on previous versions. Please submit this to the hotline so a developer can take a look.
Just upgraded to FFC 4.0.2.0 [2015.05.18 9865 01.04].
The Time Stamp variable is no longer working for us. We use it in the Save Component to add a timestamp to our file names. Since the upgrade it just leaves a blank spot in the filename.
For example:
$FFwfjob.jobName$_$FFtimeStamp$ becomes JobName_
This was working fine for us before the upgrade. Any ideas? Thanks in advance for your help!
