I'm trying to update a value that is inside a h:dataTable from a Bootstrap Modal using pure JSF 2.2 with CDI.
Here is the dataTable:
<h:dataTable id="tabNotas" value="#{notaBean.notas}" var="nota"
styleClass="table table-hover">
<h:column>
<f:facet name="header">
<h:outputText value="ALUNO" />
</f:facet>
<h:outputText value="#{nota.aluno.nome}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Disciplina" />
</f:facet>
<h:outputText value="#{nota.disciplina.nome}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="TIPO" />
</f:facet>
<h:outputText value="#{nota.tipo.descricao}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="NOTA" />
</f:facet>
<h:outputText value="#{nota.valor}" />
</h:column>
<h:column>
<h:commandLink class="btn btn-primary" value="Alterar">
<f:passThroughAttribute name="data-toggle" value="modal" />
<f:passThroughAttribute name="data-target" value="#myModal" />
<f:ajax listener="#{notaBean.editarNota(nota)}"
render="formModalNotas" />
</h:commandLink>
</h:column>
</h:dataTable>
And here is the modal:
<div id="myModal" class="modal fade">
<h:form id="formModalNotas" role="form">
<div class="modal-dialog">
<div class="modal-content">
<h:messages showSummary="true" errorClass="alert alert-danger"
infoClass="alert alert-success" for="formModalNotas" />
<input type="hidden" name="id" value="#{notaBean.nota.aluno.id}" />
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true"></button>
<h4 class="modal-title">Alterar</h4>
</div>
<div class="modal-body">
<div class="form-group ">
<label for="tipoNota">Tipo da Nota:</label>
<h:inputText value="#{notaBean.nota.tipo.descricao}"
styleClass="form-control" id="tipoNota" disabled="true" />
</div>
<div class="form-group ">
<label for="nota">Nota:</label>
<h:inputText value="#{notaBean.nota.valor}"
styleClass="form-control" id="nota" />
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default"
data-dismiss="modal">Close</button>
<h:commandButton value="Salvar" action="#{notaBean.alterar}"
styleClass="btn btn-primary">
</h:commandButton>
</div>
</div>
</div>
</h:form>
</div>
The modal works just fine, the problem is in the action="#{notaBean.alterar}" that is never called.
Am I doing something wrong? Has anyone done this before?
EDIT
I'm using Tomcat 8. Here is the code of NotaBean, I've changed to ViewScoped still nothing =/
