Yes thats right and working fine for the save node. It also works in the printing node, but if you use a tiling node in your workflow in combination of a printing node, the renaming does not work for specific variables.
In our case these are $FFwfDoc.documentWidth$ and $FFwfDoc.documentHeight$.
These variables did not work.
I stand corrected. If one specifies the use of the Workflow Job Ticket in the Save node -- see below -- the new filename is fed to the targeted second Workflow. "atlanta.pdf" becomes "atlanta-Pages-5.pdf".
Saving the file, with a new filename defined in the Save node, to a Hotfolder should result in the new filename being used. This is not working. I have written a BUG for this to be fixed.
We also had an issue with renaming printjobs, while sending them at a printer node in 6.1.3
Everything was fine by saving into file. The reason is, when i tiling node is used in the workflow, this behavior will occur in our case.
To solve this we use an external script, that writes a xpf file in front of the printer note. That file is renamed and the result is ok.
I am not able to send pictures in the forum, but I can provide you with a working example.
