How to make partial submission through a dialog called in the datatable?

Question

Hello, I have a datatable of the first faces that shows registered patients. In this datatable, I have a button that leads to a screen to inform the patient’s blood type (blood type and RH factor are class attributes Patient). If this screen to inform the blood type is in another file and I call on the datatable through a buttom with the attribute Outcome, works normally. But I want to leave this screen in a dialog and this I also got. The problem is when I click to save the blood type, I get an error message that I cannot write to the bank because the field name in Patient.java is mandatory:

This is the blood type change screen and RH factor. (Of course I replaced ui:Composition with html when calling in the dialog, so that the page does not use its own template, but rather from the datatable screen).

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
            xmlns:h="http://xmlns.jcp.org/jsf/html"
            xmlns:f="http://xmlns.jcp.org/jsf/core"
            xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
            xmlns:p="http://primefaces.org/ui"
            template="/WEB-INF/templates/Layout.xhtml">

<f:metadata>
    <f:viewParam name="paciente" value="#{pacienteBean.paciente}"/>
</f:metadata>

<ui:define name="content"> 

    <h:form id="formPaciente">
        <p:messages closable="true" severity="info,warn,error">
            <p:autoUpdate/> 
        </p:messages>
        <h:panelGrid columns="2" style="margin-left: 20px; margin-bottom: 5px">

            <p:outputLabel for="tipoSanguineo" value="Tipo sanguíneo: " />
            <p:selectOneMenu id="tipoSanguineo" style="width: 50px" value="#{pacienteBean.paciente.tipoSanguineo}">
                <f:selectItem noSelectionOption="true"/>
                <f:selectItem itemLabel="A" itemValue="A"/>
                <f:selectItem itemLabel="B" itemValue="B"/>
                <f:selectItem itemLabel="AB" itemValue="AB"/>
                <f:selectItem itemLabel="O" itemValue="O"/>
            </p:selectOneMenu>

            <p:outputLabel for="fatorRH" value="Fator RH: " />
            <p:selectOneMenu id="fatorRH" style="width: 50px" value="#{pacienteBean.paciente.fatorRH}">
                <f:selectItem noSelectionOption="true"/>
                <f:selectItem itemLabel="+" itemValue="+ (positivo)"/>
                <f:selectItem itemLabel="-" itemValue="- (negativo)"/>
            </p:selectOneMenu>

        </h:panelGrid>
    </h:form>    

    <p:toolbar id="toolbarPaciente" style="margin-top: 10px;">
        <f:facet name="left">
            <p:commandButton id="botaoSalvar" style="font-size: 13px;" value="Salvar"
                             icon="ui-icon ui-icon-disk" action="#{pacienteBean.salvar}">
                <f:ajax execute="@form" render="@form"/>
            </p:commandButton>

            <p:button style="font-size: 13px;" value="Cancelar" id="botaoDeletar"
                      outcome="/paciente/listar-pacientes" icon="fa fa-times">
            </p:button>
        </f:facet>
    </p:toolbar>
  </ui:define>
</ui:composition>

On this button, inside the datatable, I call the previous screen, which I can make the changes I need and save normally.

<p:button id="botaoDados" title="Editar" icon="fa fa-tint" style="font-size: 10px; padding-top: 5px"
                              outcome="/paciente/dados-sangue">
                        <f:param name="paciente" value="#{paciente.id}"/>
                        <p:tooltip for="botaoDados" value="Informar tipo sanguíneo"/>
                    </p:button>

In an attempt to pass this on to a Dialog, the same was true:

<p:dialog widgetVar="sanguePaciente" closable="true" draggable="false" modal="true" header="Tipo sanguíneo/Fator RH" responsive="true" 
              showEffect="fade" resizable="false" width="270" height="110" showHeader="false">
        <ui:include src="dados-sangue.xhtml" />
    </p:dialog>

And on the button, I change the Outcome to:

onclick="PF('sanguePaciente').show()"

However when I click the save button, it returns me this exception:

Caused by: javax.validation.ConstraintViolationException: Validation failed for classes [br.com.projeto.modelo.Paciente] during persist time for groups [javax.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='O nome deve ser informado', propertyPath=nome, rootBeanClass=class br.com.projeto.modelo.Paciente, messageTemplate='O nome deve ser informado'}
]

I even tried to put this first screen inside the datatable itself, without using include, but it was the same.
