Widget "path" in workflow form cannot be used twice in a row (JSF)

In Studio, create document type MyDoc with a metadata mydoc:docid of type document.

In a simple task node in a workflow, build a JSF form with content:

• Advanced Widget > Generic Widget
• Add mydoc:docid as field and path as widget type

Deploy the project, create MyDoc document and start the workflow

• Choose a path => works fine
• If now you want to choose another path for the same field => spinning wheel forever and no way to correct the input except reloading the page
