I’ve got a maven dependency with some Faces tag library descriptor.
It contains something like:
<?xml version="1.0" encoding="UTF-8"?>
<facelet-taglib version="2.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd">
When the corresponding namespace (http://abc.com/core) is defined in my faces xhtml file, IDEA says: URI is not registered.
But it doesn’t complain about http://abc.com/b namespace which is defined in the same library in another descriptor file.
The only difference between these 2 descriptor files is <composite-library-name>, which is not in the second one.
When I open this "problem" descriptor file in my project, IDEA colors "abc/core" in red and says: Cannot resolve library. But if I create such project with these tag library descriptor files in IDEA, everything can be resolved and even I can navigate to this abc/core directory.
The question is, why this namespace which contains <composite-library-name> tag is considered to be not registered URI?
