Not compatible with TemplateData   WikipediaTemplateData is a brand new feature which is apparently not fully compatible with wikEd   Pick a template doc subpage eg TemplateCroatian Census doc  Click on Edit  Click on the Manage TemplateData button  Change something in the popup form eg the description  Click on the Apply button  Now changes made to template data should be propagated to the edit area  element but they are not The workaround is to switch wikEd off when working with TemplateData form or to use the edit area directly rather than the form
