    [ https://issues.jboss.org/browse/JBIDE-22886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276455#comment-13276455 ] 

Viacheslav Kabanovich commented on JBIDE-22886:
-----------------------------------------------

For me, it works this way: 
If the definition of a composite component tag declares
{code}
     <html ...  xmlns:composite="http://java.sun.com/jsf/composite">
{code}
then in order to access that tag a page should import the component as
{code}
<html ... xmlns:mycomp="http://java.sun.com/jsf/composite/mycomp">
{code}
Otherwise, if the definition of a tag declares
{code}
    <html ... xmlns:composite="http://xmlns.jcp.org/jsf/composite">
{code}
then in order to access it the page should import the component as
{code}
    <html ... xmlns:mycomp="http://xmlns.jcp.org/jsf/composite/mycomp">
{code}
If the folder mycomp has different tag definitions some of them with /xmlns.jcp.org/ and others with /java.sun.com/ it is possible to import all of them with two namespaces like
{code}
<html ... 
    xmlns:mycomp1="http://java.sun.com/jsf/composite/mycomp"
    xmlns:mycomp2="http://xmlns.jcp.org/jsf/composite/mycomp">
{code}

Does this logic seems correct? 
[~karlnicholas], please check if the issue is caused by an auto-build problem. I could not reproduce it, but please check, if clean/build of the project helps when reported warning is incorrect (provided the match of URI in the tag definition and the import as I have described).
