<my:foo> Tag Library supports namespace: http://java.sun.com/jsf/composite/mycomponents, but no tag was defined for name: foo -


i have composite component named <my:foo> , i'm building composite component named <my:bar>. when attempt use <my:foo> inside <cc:implementation> of <my:bar>, following exception been thrown:

<my:foo> tag library supports namespace: http://java.sun.com/jsf/composite/mycomponents, no tag defined name: foo

how caused , how can solve it?

this caused bug introduced in mojarra 2.1.8, continued in 2.1.9 , fixed in 2.1.10. bug causes composite component's own xml namespace cannot declared in root xml element <ui:component>/<ui:composition>/<html>/etc follows:

<ui:component      xmlns="http://www.w3.org/1999/xhtml"     xmlns:f="http://java.sun.com/jsf/core"     xmlns:h="http://java.sun.com/jsf/html"     xmlns:ui="http://java.sun.com/jsf/facelets"     xmlns:cc="http://java.sun.com/jsf/composite"     xmlns:my="http://java.sun.com/jsf/composite/mycomponents" >     <cc:interface>         ...     </cc:interface>     <cc:implementation>         <my:foo />     </cc:implementation> </ui:component>

this result in following exception when attempt nest <my:foo> inside <cc:implementation>.

<my:foo> tag library supports namespace: http://java.sun.com/jsf/composite/mycomponents, no tag defined name: foo

the current workaround, apart downgrading 2.1.7 , waiting 2.1.10 released, move xml namespace declaration <cc:implementation>.

<ui:component      xmlns="http://www.w3.org/1999/xhtml"     xmlns:f="http://java.sun.com/jsf/core"     xmlns:h="http://java.sun.com/jsf/html"     xmlns:ui="http://java.sun.com/jsf/facelets"     xmlns:cc="http://java.sun.com/jsf/composite" >     <cc:interface>         ...     </cc:interface>     <cc:implementation xmlns:my="http://java.sun.com/jsf/composite/mycomponents">         <my:foo />     </cc:implementation> </ui:component>
