update parameter in Java Primefaces - primefaces

Question

My problem is kinda tricky, I hope u get my explanation, I'll be as clear as I can with this.
I have a DataTable that displays a button to see the activities related with the selected item. this opens a little panel with a menu, that at the moment has only one option. This opens yet another panel with 2 forms, in with I do what I need to.
My problem comes when I use the update parameters to add the info I need into the DB.
this is the code for the button I'm using.
<p:commandLink action="#{reporteConsultorBean.verActividades(lead)}" update=":formMain:panelViewNotas" title="Ver actividades asociadas al Expediente">
<center>
<p:graphicImage value="/images/actividad32.png" />
</center>
</p:commandLink>
this is the dialog that pops out once you clicked the button.
<p:dialog id="idDialogActitividades" header="Actividades del Expediente"
widgetVar="dialogActividades" resizable="true"
showEffect="slide" hideEffect="fade">
<center>
<p:panel header="Actividades del Expediente" >
<p:panelGrid columns="1">
<p:commandLink title="Notas" onclick="dialogNotaView.show(); return false;" style="margin:0 auto">
<center>
<p:graphicImage value="/images/nota.png"/>
</center>
</p:commandLink>
</p:panelGrid>
<br/>
<p:panelGrid columns="1" >
<p:commandLink title="Cerrar" onclick="dialogActividades.hide(); return false;" style="margin:0 auto">
<p:graphicImage value="/images/cerrarBoton.png"/>
</p:commandLink>
</p:panelGrid>
</p:panel>
<br />
</center>
</p:dialog>
and this is the form in which you save the data to de DB.
<p:dialog header="Notas del Expediente" width="950"
widgetVar="dialogNotaView" resizable="true" minWidth="950"
showEffect="slide" hideEffect="fade">
<p:panelGrid columns="2" width="930">
<p:panelGrid columns="1" width="75">
<p:commandLink title="Notas" onclick="return false;" style="margin:0 auto">
<center>
<p:graphicImage value="/images/nota.png"/>
</center>
</p:commandLink>
</p:panelGrid>
<p:panel id="panelViewNotas" header="Notas del Expediente" width="830">
<center>
<h:form id="formNotas">
<p:messages id="messagesNotas" showDetail="true" autoUpdate="true" />
<p:panelGrid id="panelTabNotas" columns="2" width="800">
<f:facet name="header">
Nota
</f:facet>
<p:graphicImage value="/images/nota.png" />
<h:outputText value="Nota" />
<h:outputText value="" />
<h:outputText value="" />
<h:outputText value="Nombre/Tema *" />
<p:inputText value="#{reporteConsultorBean.notaView.nombre}" required="false" requiredMessage="Es necesario que ingrese el asunto"
size="50" maxlength="49" />
<h:outputText value="Descripción *" />
<p:inputTextarea value="#{reporteConsultorBean.notaView.descripcion}" rows="4" cols="65" maxlength="270"
required="false" requiredMessage="Es necesario que ingrese la descripción de la nota." />
</p:panelGrid>
<br/>
<p:panelGrid columns="2" >
<p:commandLink actionListener="#{reporteConsultorBean.saveNota}"
update=":formMain:growl,:formMain:formNotasResult:panelResultadoNotas,:formMain:formNotas:panelTabNotas,:formMain:formNotas:messagesNotas" title="Guardar Nota" style="margin:0 auto" >
<center>
<p:graphicImage value="/images/guardarBoton.png"/>
</center>
</p:commandLink>
<p:commandLink title="Cerrar" onclick="dialogNotaView.hide(); return false;" style="margin:0 auto">
<center>
<p:graphicImage value="/images/cerrarBoton.png"/>
</center>
</p:commandLink>
</p:panelGrid>
</h:form>
<br/>
<p:separator style="width:700px;height:10px" />
<br/>
<h:form id="formNotasResult">
<p:panel id="panelResultadoNotas" header="Notas del Expediente" width="830">
<p:dataTable id="tablaNotasResumen" var="notaResumen"
value="#{reporteConsultorBean.notasExp}" rowKey="#{notaResumen.idNota}"
paginator="true" rows="4" emptyMessage="No hay registros"
selectionMode="single" selection="#{reporteConsultorBean.notaSelected}">
<p:column headerText="Nombre/Asunto">
#{notaResumen.nombre}
</p:column>
<p:column headerText="Descripción"> #{notaResumen.descripcion}
</p:column>
<p:column headerText="Creador">
#{notaResumen.actividad.creador}
</p:column>
<p:column headerText="Fecha Creación">
<h:outputText value="#{notaResumen.actividad.fechaCreacion}">
<f:convertDateTime type="date" pattern="dd-MM-yyyy"/>
</h:outputText>
</p:column>
<p:column>
<p:commandLink title="Editar Nota"
update=":formMain:formNotas:panelTabNotas"
action="#{reporteConsultorBean.editarNota(notaResumen)}">
<p:graphicImage value="/images/editarBoton.png" />
</p:commandLink>
</p:column>
</p:dataTable>
</p:panel>
</h:form>
</center>
<br/>
</p:panel>
my problem comes when I use "panelViewNotas" in the button above. When I use it everything is displayed as it should, but when I hit the "Save" button on the last form, nothing happens (not even a nullPointerException in the Log or Tomcat).
and when I use:
update=":formMain:formNotasResult:panelResultadoNotas,:formMain:formNotas:panelTabNotas"
the data gets stored in the DB with no problem, but the View of the whole thing gets messed up "DialogNotaView" it shows one form in top of the other.
I hope you understand this problem and that u can help me.
How can I fix this problem?
