It appears that 2 "Automatic" press sheet sizes were designated. When using the "Automatic" press in the Workflow, one the Size Options is "Automatic". If this option is removed (top picture), the job will process without the size error. See below:
I see the problem. I do not know of the reason for the error -- or a workaround. I have written a BUG against this.
I can't determine from the video what the cause of the problem is. It appears (from the error message) that one dimension of the press sheet gets defined with a length of 0 -- which obviously does not work.
Would it be possible to attach the Hotfolder/Workflow and input document? I may be able to replicate the problem then.
When do you see the error message? When saving the node? Processing a job? I am not seeing a problem when I select "automatic" as the press sheet size and I do not select a "custom size".
I am using 7.0.2. I am assuming that you are referring to the below highlighted choices. I am seeing them. Is it something else that is not appearing?
