When the save button is on the page it works normally and saves the entity but I open a dialog to confirm the data to be saved and Hibernate saves twice very strange method to save outside the dialog works properly but inside runs twice.
<p:dialog id="dialogconfirmarvenda" appendTo="@(body)" widgetVar="dcv" closable="true" width="1000" maximizable="true" binding="#{vendaMB.dialogconfirmarvenda}" minimizable="true" position="top">
<p:ajax event="close" listener="#{vendaMB.closeDialog()}" />
<f:facet name="header"><h:outputText value="CONFIRMAR VENDA" style="font-family: sans-serif"/></f:facet>
<h:form id="formfinalizarvenda">
<p:panelGrid id="panelgridconfirmarvenda">
<p:row>
<p:column rendered="#{vendaMB.clienteMB.clienteDAO.cliente != null}"><h:outputText value="Cliente" styleClass="text"/></p:column>
<p:column rendered="#{vendaMB.clienteMB.clienteDAO.cliente != null}"><h:outputText value="#{vendaMB.clienteMB.clienteDAO.cliente.nome}" styleClass="text"/></p:column>
<p:column><h:outputText value="Pagamento" styleClass="text"/></p:column>
<p:column><h:outputText value="#{vendaMB.meioPgtoMB.meioPgtoDAO.meiopgto.descricao}" styleClass="text"/></p:column>

<p:column><h:outputText value="#{vendaMB.totalVenda}" styleClass="text"><f:convertNumber type="currency"/></h:outputText></p:column>
<p:column>
<p:commandButton actionListener="#{vendaMB.finalizarVenda()}" value="Finalizar" oncomplete="PF('dcv').hide()"/>
</p:column>
</p:row>
</p:panelGrid>
<p:spacer height="10" width="800"/>
<p:dataTable id="tableitensvenda" value="#{vendaMB.itemvendaAdds}" var="ivadd">
<p:column headerText="Código"><h:outputText value="#{ivadd.itemvenda.produto.codigo}"/></p:column>
<p:column headerText="Produto"><h:outputText value="#{ivadd.itemvenda.produto.descricao}"/></p:column>
<p:column headerText="Preço">
<h:outputText value="#{ivadd.itemvenda.valor}">
<f:convertNumber type="currency"/>
</h:outputText>
</p:column>
<p:column headerText="Qtd"><h:outputText value="#{ivadd.itemvenda.quantidade}"/></p:column>
<p:column headerText="Total"><h:outputText value="#{ivadd.total}"><f:convertNumber type="currency"/></h:outputText></p:column>
</p:dataTable>
</h:form>
</p:dialog>
This is the dialog to display the data for confirmation. The link that opens the dialog:
<p:commandLink value="venda" title="Confirmar Venda" oncomplete="PF('dcv').show()" actionListener="#{vendaMB.confirmarVenda}" />
public void confirmarVenda() {
for (Meiopgto meiopgto : meioPgtoMB.getMeiopgtos()) {
if (meiopgto.getIdmeiopgto().equals(idmeiopgto)) {
meioPgtoMB.getMeioPgtoDAO().setMeiopgto(meiopgto);
break;
}
}
RequestContext.getCurrentInstance().update(Arrays.asList("formvenda", "dialogconfirmarvenda"));
}

Ronaldo, could include the code of the button that opens the
Dialog? My guess is that the button has aactioncalling the methodvendaMB.finalizarVenda(), and in addition to opening theDialoghe saves the information.– Wakim
Do not forget to make a mention (@Name), otherwise I am not notified. My suggestion would be to put a Breakpoint in the method that is called twice and look at the stacktrace to see what it is called in those two times. This may give a hint of the problem.
– Wakim
Ronaldo, I wanted you to put one Breakpoint and debug in the method that calls to JPA. And if possible include the stacktrace that appears in the Debug perspective.
– Wakim
Some possibilities (the problem of not having one MVCE is not being able to state anything accurately). Is your dialog not inside a form and this is firing the event twice? Did some other
listeneras#{vendaMB.closeDialog()}or#{vendaMB.finalizarVenda()}is not calling this method?– Anthony Accioly
@Anthony Accioly I removed the Binding="#{saleMB.dialogconfirma sale}" and it worked - I don’t know why - and thanks for the help.

@Ronaldosantos, as you may have seen in the [tour], you can accept a response, do not use the "Solved" approach in the title as is usually done in forums. In this question, you could elaborate an answer telling how you arrived at the solution and then accept it.
