Descriptions

application-collabora is an integration of Collabora Online in XWiki. As part of the application use cases, depending on the rights that a user has over a document, they should be able to open the office attachments files in view or edit mode. Currently, if a user opens an attachment file in edit mode in collabora, this right will be preserved for all future users, until the editing session is closes, even if some of them have only view right. Collabora server is the one issuing this request and it seems that the `userCanWrite` query parameter is cached, even if, for example, token is not. This issue has been patched in version 1.3.

application-collabora es una integración de Collabora Online en XWiki. Como parte de los casos de uso de la aplicación, dependiendo de los derechos que tenga un usuario sobre un documento, debería poder abrir los archivos adjuntos de Office en modo de visualización o edición. Actualmente, si un usuario abre un archivo adjunto en modo de edición en collabora, este derecho se conservará para todos los usuarios futuros, hasta que se cierre la sesión de edición, incluso si algunos de ellos solo tienen derecho de visualización. El servidor de Collabora es el que emite esta solicitud y parece que el parámetro de consulta `userCanWrite` está almacenado en caché, incluso si, por ejemplo, el token no lo está. Este problema se solucionó en la versión 1.3.
