This has been happening for a long time - probably as far back as 8.3. What happens is that when the Designer validates the workflow before publishing, it occasionally gives errors saying that X activity is invalid because Y activity (which it depends on) doesn't exist - even though it does. The fix is easy enough, we just go into the X activity and change it to run on the Starting Entry, then back on the output of the Y activity, and it works then. But I'm wondering why the validation occasionally fails.

Has anyone else seen this? It's a very intermittent issue and can't be reproduced on demand, which is why we haven't opened a support case, but I'm wondering if it's a known issue on Laserfiche's end.
