Not possible to create field with field type “parent” via GUI

[heidivanparys]

I followed the step-by-step guidance at https://github.com/ec-jrc/re3gistry/issues/42#issuecomment-829172097 to create a register that can contain hierarchical code lists.

However, what is described for step 2.6 / 3.2 does not work for me.

• The field with name “parent” and type “parent” is not present (I don't know whether it is supposed to be a field that should be present from the start, as the field “definition” e.g.)
• It is not possible to create a new field with type “parent”, see screenshot.

A workaround was to create a new field with type e.g. “text”, and then change its field type to “parent” (uuid = '7') directly in the database:

That new field could then be used in the item class:

@oscar9 The same problem happens as well with the successor and predecessor. When an item is superseded the successor/predecessor doesn't appear. Probably the best is to add the 3 fields in the init script of the database, or to create on the fly successor/predecessor fields when there is a supersession, but this wouldn't solve the parent problem.

OR in this page should be given the option in the dropdown menu for the field type to choose: parent/successor or predecessor.
