Empty variable when open <p:dialog> - JFS 2.0, Primefaces - jsf

Question

how're you?
Maybe a newbie question now. Now I have one input and a "submit" button inside a form. When I click in submit, this doesn't call any method, this just opens a <p:dialog>. When this dialog is opened, the variable in input wasn't setted, so another input I have in doesn't show anything.
See the images to understand:
After click in "submit" (Adicionar):
This second image must show exactly the same value of the first input, but as you can see this just shows a empty input.
Now let's go to my code.
Here's my JSF:
<h:form id="inserirDisciplina">
<h:inputText styleClass="form-control" id="disciplina" value="#{cursoMBean.nome}"
valueChangeListener="#{cursoMBean.atualizarListagemPesquisa}">
// atualizarListagemPesquisa just update the arraylist to be shown in dataTable
<f:ajax event="keyup" render=":meuForm:minhaTabela" />
</h:inputText>
<h:commandButton value="Adicionar" styleClass="btn btn-md btn-success">
<p:ajax event="click" update=":meuForm:display" render=":meuForm:dialog" oncomplete="PF('insert').show();" onerror="alert('erro');" />
</h:commandButton>
<p:dialog id="dialog" header="Inserir Curso" widgetVar="insert" resizable="false" modal="true" width="600" height="500" hideEffect="clip" closeOnEscape="true" focus="enviar">
<h:panelGrid id="display" styleClass="col-lg-10 center">
<label for="nome">Nome:</label>
<p:inputText styleClass="form-control adicionar" id="nome" value="#{cursoMBean.nome}" />
</h:panelGrid>
...
MBean:
private String nome;
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
Edit (new View):
<h:form id="inserirDisciplina">
<div class="form-group">
<div class="col-md-10">
<h:inputText styleClass="form-control" id="disciplina" value="#{cursoMBean.nome}" valueChangeListener="#{cursoMBean.atualizarListagemPesquisa}">
<f:ajax event="keyup" render=":meuForm:minhaTabela" />
</h:inputText>
</div>
<div class="col-md-2">
<h:commandButton value="Adicionar" styleClass="btn btn-md btn-success" process="disciplina" partialSubmit="true">
<p:ajax event="click" update=":meuForm:display" render=":meuForm:dialog" partialSubmit="true" process="disciplina" oncomplete="PF('insert').show();" onerror="alert('erro');" />
</h:commandButton>
</div>
</div>
</h:form>
<p:messages autoUpdate="true" />
<p:dialog id="dialog" header="Inserir Curso" widgetVar="insert"
resizable="false" modal="true" width="600" height="500"
hideEffect="clip" closeOnEscape="true">
<h:form>
<h:panelGrid id="display" styleClass="col-lg-10 center" style="margin-top: 10px; margin-bottom: 15px;">
<label for="nome">Nome:</label>
<p:inputText styleClass="form-control adicionar" id="nome" value="#{cursoMBean.nome}">
</p:inputText>
</h:panelGrid>
<h:panelGrid styleClass="col-lg-10 center">
<p:columnGroup>
<label for="disciplinas">Disciplinas do Curso:</label>
<h:selectManyCheckbox style="margin-bottom: 40px;" id="disciplinas" value="#{cursoMBean.listaDisciplinasDoCurso}" converter="omnifaces.SelectItemsConverter">
<f:selectItems value="#{cursoMBean.listaTodasDisciplinas}" var="disciplina" itemValue="#{disciplina}" itemLabel="#{disciplina.nome}" />
</h:selectManyCheckbox>
</p:columnGroup>
</h:panelGrid>
<h:panelGrid styleClass="col-lg-10 center">
<p:columnGroup>
<h:commandButton id="enviar" styleClass="btn btn-lg btn-success pull-right" value="Adicionar" action="#{cursoMBean.cadastrar}">
<f:ajax event="click" execute="#form" onevent="insert.hide()" render=":meuForm:minhaTabela" listener="#{cursoMBean.cadastrar}" />
</h:commandButton>
</p:columnGroup>
</h:panelGrid>
</h:form>
</p:dialog>
What I'm doing wrong?

Answer 1

Try the following code for the button:
<p:commandButton value="Adicionar" styleClass="btn btn-md btn-success"
process="disciplina" partialSubmit="true" update=":inserirDisciplina:display"
oncomplete="insert.show();" onerror="alert('erro');">
</p:commandButton>
