Change WF export to PDF, WF editor performance

Change WF export to PDF, WF editor performance

Hi,
I have noticed that the Export as PDF function in Change Workflow Editor generates only the header and footer (see attachment) if the WF is bit more complex (close to 80 nodes, stages with 7-8 statuses, multiple switches with +-5 values each). 

In addition the overall performance of the Workflow Editor is very poor.
I'm having 5-10s lags when dragging or editing nodes.
Saving the WF takes ages (10-15min if it even finishes) and then half the times produces not so helpful error messages.

For example (screenshots in attachment):
Unable to parse the given data for y
Please provide a valid input for field statements
Please provide a valid input for field connectors

None of those gives me any idea what exactly is wrong, if anything, because if I exit the editor chosing not to save changes then reopen the WF the changes I made have been saved anyway. ??

Could someone please look into that?


As a sidenote, being able to select multiple nodes and move them at the same time would be huge time saver when you need to extend some sturture in the middle of the WF. At this moment it means moving +-20-30 nodes manually with 5-10s lag on each to make additional room.

Thanks.

Best regards,
A.D.
