Problems using Myfaces1.1 - can't find tld files

Question

I have used Nitrox 2.1 with Myfaces 1.0 - everything was fine, but now we're changing to Myfaces1.1. All I do is changing the old myfaces.jar with the newer myfaces-all.jar (ver 1.1.1). The problem is that Nitrox IDE doesn't seem to recognize the tlds in this jar-file.
When I run the jsf everything is as expected, it reads the jar, but in the editor the page is full of warnings saying "The tag library uri "http://java.sun.com/jsf/html cannot be mapped to an existing tld file". The same is for http://java.sun.com/jsf/core and http://myfaces.apache.org/extensions. It doesn't understand any of the JSF-tags (or myfaces). This also mean that the intellisense doesn''t work - not very easy to work this way. Of course I have included the jar in the classpath - it obviously reads the jar since it works when running.
Is this a known problem? What may possibly be wrong?

Answer 1

Nope, this is not an issue and it should work fine with myfaces-all.jar file. Please try the following steps and update whether this fixed the issue:
NOTE: Assume myfaces-all.jar file is listed at Project > Properties > Java Build Path > Libraries tab
- Open any page that is complaining about the tag library
- in the source editor put the cursor within <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
- from the Smart Editor click on the button next to URI - Do you see the entry TLDs from /WEB-INF/lib/myfaces-all.jar file?
If not, then try these steps:
- Project > Close Project
- Project > Open Project
- and then Project > Clean... - this will also rebuild the project
- At the end of this, all warnings related to tag library should be removed
