Topic on Extension talk:TemplateData

In our case once upon a long time ago the database got borked (not by me) on upgrade and it was repaired, I think this issue stems from that as I've ruled out everything else systematically. Works on a clean site with pages imported, I'll do that.

How are "params" entered using the "Manage Template Data" button? Can they not be added this way? At current it looks like it's possible to add these but only manually, why? Or if it is possible to add it via the "Manage Template Data" button, how?

"sets": [
          {
            "label": "Date",
            "params": ["year", "month", "day"]
          }
        ]

Also, can someone help in determining why VE can't see the Template Data for templates?
