[EP-tech] Short workflow

Hi everyone,

we had the idea to offer a single-stage submission workflow after complaints of 
a VIP at our university that the current workflow requires too many clicks.

This short workflow would be activated after an import of an item from 
Crossref, PubMed, ORCID or another source (e.g. at the first revision of the 
item and if the source is known), and would only offer the missing required 
fields and the upload component. For many users (we have several hundred 
submitters adding more than 10'000 items annually), this would save hours of 

However, after implementing such a single stage, we observed that some 
components have the following problems if merged into one stage with other 
- the Subject component crashes the application  after choosing a subject for 
adding   (leading to a "Can't call method "get_state_params" on 
an undefined value at /service-app/apps/eprints/perl_lib/EPrints/Workflow.pm 
line 499.\n" error).
- the Upload component does not return feedback when uploading a document (it 
goes on infinitely). After interruption, however, the system indicates that the 
document had been uploaded and is there.

Definitely something is wrong with the workflow engine. In my opinion, 
components should be freely includable in whatever part of the stage.

Has anybody else tried to achieve something similar and had success?

Kind regards,
