This is a simple page using a JSF input component from tomahawk library:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>
<html>
<head><title>Simple jsp page</title></head>
<body>
<f:view>
<h:form>
<t:inputText/>
</h:form>
</f:view>
</body>
</html>
IDEA show this error validating the page:
"Error: javax/faces/webapp/UIComponentTag"
I created a standard project with myfaces JSF 1.1 implementation but the same problem arises using JSF 1.1 reference impl. from Sun and using other taglibraries.
If I disable JSP validation the application builds correctly and also behaves correctly after deploy.
