HTTP Status 500 - Internal Server Error

[my face <jsf-dev@xxxxxxxx>]

Hi,

 

The objective is to concatenate the literal string to field of the injected class

for output valued _expression_.

 

why should  adding the word Go in single quote cause this error ?

Has the specification changed  ?

 

  <h:commandButton
      value="#{'Go ' + xyz.submit}"  <!-- rvalue -->
      action="" <!-- go() method -->
