I've simplified test case to illustrate that the bug is actually in facelets library tag1 | | <?xml version="1.0" encoding="iso-8859-1"?> | <ui:component xmlns="http://www.w3.org/1999/xhtml" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:fc="http://java.sun.com/jstl/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:w="http://test.org/tags" | xmlns:f="http://java.sun.com/jsf/core"> | <div> | tag1 | <w:tag2> | <ui:insert></ui:insert> | </w:tag2> | tag1 | </div> | </ui:component> | | tag2 | | <?xml version="1.0" encoding="iso-8859-1"?> | <ui:component xmlns="http://www.w3.org/1999/xhtml" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:fc="http://java.sun.com/jstl/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:w="http://test.org/tags" | xmlns:f="http://java.sun.com/jsf/core"> | <div> | tag2 | <ui:insert></ui:insert> | tag2 | </div> | </ui:component> | | | | <h:form id="testTags"> | <w:tag1> | <div> | Hello1 | </div> | </w:tag1> | <w:tag2> | <div> | Hello2 | </div> | </w:tag2> | </h:form> | | Hello1 is not rendered (as it should have) with facelets 1.1.13a (Seam 2.0.0.Beta1) Hello1 is rendered with facelets from JBoss Seam 1.3.0.ALPHA I hope this provides enough evidence for facelets developers to look at it...
