Ao adicionar a tag ajax o projeto e agora dá erro…
Fiz assim:
<h:panelGrid >
<h:outputLabel value="Diretor de turma:" for="ddt" />
<h:selectOneRadio id="ddt"
value="#{professorBean.professor.diretorDeTurma}">
<f:selectItem itemLabel="Sim" itemValue="Sim" />
<f:selectItem itemLabel="Nao" itemValue="Nao" />
<f:ajax event="click" render="opcoes" />
</h:selectOneRadio>
</h:panelGrid>
<h:panelGrid id="opcoes">
<h:outputLabel value="Turma:" for="responsavel" />
<h:inputText id="responsavel"
value="#{professorBean.professor.turma}" />
</h:panelGrid>
E dá esse erro:
<f:ajax> Tag Library supports namespace: http://java.sun.com/jsf/core, but no tag was defined for name: ajax
Como resolvo?
