Problems with ajax4jsf and view-handler
hello together
i enhanced the helloworld example with different components.
now i try to work with the ajax4jsf:poll component!
i added the ajax4jsf component as decribed.
after deploy an start of the project my form-items not got rendered.
(input-fields, buttons)
if i uncomment the view-handler from the faces-config.xml,
the standard elements got rendered but i got a xml parser error,
because it finds not the ajax4jsf namespace!
XML Parsing Error: prefix not bound to a namespace
thanx for help!
greetings daniel
