For a project, we have added some extended fields on contents. Those fields use KeywordWidget widget (same as Plone ‘Subject’ tags).

We wanted to have a custom permission on those fields, so we used :


But it didn’t work : the field title and label displayed correctly (when we have the permission) but the widget never happeared.

Why ?

Because the KeywordWidget template use allowRolesToAddKeywords (from portal_properties / site_properties) to filter who can add new keywords. So that “permission” will impact your custom fields too !

There has been tickets / discussion about allowRolesToAddKeywords, but that never changed.

Hope that noone else would get bitten by this once-for-all permission on keyword widgets.
