It's still not perfect, see http://jira.xwiki.org/jira/browse/XWIKI-3780 and http://jira.xwiki.org/jira/browse/XWIKI-3649 > But this mechanism does not contemplate cross page duplicated items. > > To avoid the following error: > > Property ID "lipsum" (found on "fo:block") previously used; ID values > must be unique within a document!

It's not that simple, the problem is that the ids are currently generated in the parser which has no idea what is the document. > Will someone point out the best place to do this? There should be a protection in XHTML renderer for sure anyway since it's supposed to produce valid XHTML whatever the cost even if it means changing ids that are expected by some link. Then depending of the issue there should be improvement where possible like some refactoring in the include macro to fix XWIKI-3649. > If I post a patch with this fix will it be included on the trunk? > > Thank you in advance, > > » Ricardo Espírito Santo > » Linkare TI - Tecnologias de Informação, Lda > _______________________________________________ > devs mailing list > [email protected] > http://lists.xwiki.org/mailman/listinfo/devs > -- Thomas Mortagne _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
