With YAMS multiple language variants of content are embedded in documents during the parsing process. Thus there may be several language variants of the eForm form embedded in the document at the time the eForm plugin is active, even though only one version of the form will finally appear on the page. If each embedded eForm has the same form-id, then this will cause eForm to get confused. Therefore, to embed eForm in a multilingual document it is necessary to use one set of templates per language, and to give each a unique form-id.
