Workflow section cannot be modified from the GUI

Hi @ladinesa, as discussed together already, I raise this issue about the editability of the workflow section from the GUI.

The tasks, inputs and output appear like editable fields, if you try to fill them and save, the entry will raise an error. You can reproduce this generating an entry from any of the schemas available in "create from schema"

Connected to this, would be useful to allow to fill from the GUI the tasks fetching from the "data" section. I'm not sure how is the current behaviour.

Thanks
