    You did not declare the t namespace (there is no xmlns:t="..." in your JSF). You need to declare this using the appropriate namespace URI. Commented Jul 17, 2017 at 12:56
  • Because I received negative feedback on this question? Commented Jul 18, 2017 at 17:07
  • I don't know why people vote your question down. But you better get used to that if you ask questions on StackOverflow - it's often not a friendly place for people who ask questions... Commented Jul 18, 2017 at 19:24

According with @Jesper

You are trying to acces a library that you didn't declare where to found it.

This 't' is a namespace that you didn't daclare.

Example: Here you use <f:view> and this 'f' is a namespace for this URL :

xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"

So you are using a namespace undefined, check out the URL for this namespace 't'

Try this:

xmlns:t="http://myfaces.apache.org/tomahawk"

I think if you don't include the library and the assigned prefix (xmlns:t), you can not use it.
