update entity attribute through primefaces modal - jsf-2

Question

Try to load and update attributes from a datatable to a form embedded in a primefaces modal box:
1) The datatable command to send user's data to the modal
<p:commandButton value="alterar"
action="#{usuarioMB.carregarAlteracao(u)}" update=":usuarioDesc"
process="#this" onclick="dlg.show();" />
2) It loads well the user's attributes in the modal box
<p:dialog id="modalDialog" header="Alterar Usuário" widgetVar="dlg"
modal="true" height="260" appendToBody="true" dynamic="true" >
<h:form id="usuarioDesc" styleClass="formTamanho">
<h:panelGrid id="#{msg.pnlIdProfile}" columns="2"
columnClasses="labelPanelGrid, contentPanelgrid">
<p:outputLabel value="Perfil:" />
<p:outputLabel value="#{usuarioMB.usuario.perfil.nome}" />
</h:panelGrid>
<h:panelGrid id="#{msg.pnlIdLogin}" columns="2"
columnClasses="labelPanelGrid, contentPanelgrid">
<p:outputLabel value="#{msg.lblLogin}" for="usuario_login" />
<p:inputText value="#{usuarioMB.usuario.login}" id="usuario_login"
required="true" requiredMessage="#{msg.msgReqLogin}" />
</h:panelGrid>
<h:panelGrid id="nomeUsuario" columns="2"
columnClasses="labelPanelGrid, contentPanelgrid">
<p:outputLabel value="Nome:" for="usuario_nome" />
<p:inputText value="#{usuarioMB.usuario.nome}" id="usuario_nome"
required="true" />
</h:panelGrid>
<h:panelGrid id="emailUsuario" columns="2"
columnClasses="labelPanelGrid, contentPanelgrid">
<p:outputLabel value="Email:" for="usuario_email" />
<p:inputText value="#{usuarioMB.usuario.email}" id="usuario_email"
required="false" />
</h:panelGrid>
<h:panelGrid id="#{msg.pnlIdCal}" columns="3"
columnClasses="labelPanelGrid, contentPanelgrid">
<p:outputLabel value="#{msg.lblBirth}" for="#{msg.calId}" />
<p:calendar value="#{usuarioMB.usuario.nascimento}"
id="#{msg.calId}" locale="#{msg.calLocale}" showButtonPanel="true"
navigator="true" />
<p:outputLabel value="(Ex: 16-04-1980)" />
</h:panelGrid>
<br />
<div id="btnForms" style="margin-left: 120px;">
<p:commandButton value="Alterar Usuário" id="alt_usuario"
action="#{usuarioMB.alterar()}" update=":usuarioDataTable:tableUsuarios"
process="#this" style="margin-left:5px;" oncomplete="dlg.hide();"/>
<p:commandButton value="Criar nova senha e mandar por email"
id="alt_senha"
action="#{usuarioMB.sendEmail(usuario.email)}"
process="#this"
style="margin-left:5px;" />
<p:commandButton value="Cancelar" onclick="dlg.hide();"
style="margin-left:5px;" />
</div>
</h:form>
</p:dialog>
3) When i modify the attribute through the fields in the modal, then use the command action "alterar" , then the managed bean still keeps the reference to the user's original datas, and no update happens.
public String alterar() {
try {
gerenciarUsuarioBean.alterar(usuario);
JSFMessageUtil.sendInfoMessageToUser("Usuário salvado com sucesso!");
} catch (DaoExcecao e) {
LOG.error(e);
JSFMessageUtil.sendErrorMessageToUser("Erro cadastrando usuário !");
}
usuario = new Usuario();
return "/views/gerencia/gerenciarUsuarios.xhtml";
}
In a nutshell, the user's attributes are auto merged in the database. Any help is welcome..

Ok, then there was a bit of confusion in the command buttons (process / update)
1) datatable cmd:
<p:commandButton value="alterar"
action="#{usuarioMB.carregarAlteracao(u)}" update=":usuarioDesc:usr"
process="#this" onclick="dlg.show();" />
2) Update button
<p:commandButton value="Alterar Usuário" id="alt_usuario"
action="#{usuarioMB.alterar()}"
update=":usuarioDataTable:tableUsuarios" process="#form"
style="margin-left:5px;" oncomplete="dlg.hide();" />
Hope it helps someone.
