JSF + Tomahawk component NullPointerException

Question

Hi All,
I made a sun JSF portlet by using the tomahawk 1.1.3 file upload component. The bean "UploadedFile myFile" is not getting set in the "MyBean.java" file. I get a java.lang.NullPointerException when I am trying to myFile.getName() or myFile.getInputStream().
The inputFileUpload method should set the myFile Bean but it seems like its not getting set

2 <t:inputFileUpload id="myFileId"
3            value="#{myBean.myFile}"
4 storage="file"
5 required="true"/>
6 <h:message for="myFileId"/>
I am attaching the whole code below
Can somebody please help me. I have tried various versions of tomahawk and still not able to figure out the problem.
I am using JSF 1.1.0 and tomahawk 1.1.3
Please let me know if you need some more information from me

You cannot mix differnet JSF implementations. Use the one or the other.
As you stated that you're "using" Mojarra, get rid of those myfaces jars.
