Here is the source code producing your problem:
ComponentContext compContext = (ComponentContext)pageContext.getAttribute(
ComponentConstants.COMPONENT_CONTEXT, pageContext.REQUEST_SCOPE);
if( compContext == null )
throw new JspException ( "Error - tag useAttribute : no tiles context
found." );
If this happens intermittently then maybe it is because a user is hitting
the back button or a cached page or something like that which would cause
the request to be missing the component context.
Just a guess.

Subject: Error - tag useAttribute : no tiles context found.
I am using tiles:useAttribute tag to define a variable in request scope for
the remaining page to reference like this:
<tiles:useAttribute name="menuon" scope="request" ignore='true'/>
The runtime complains about tiles context not found as follow:
javax.servlet.jsp.JspException: Error - tag useAttribute : no tiles context
found.

The application works fine with intended functionalities, but this exception
fills my log file all over. Any idea what could cause this?
