How to assign new Selectonemenu value to entity?

Question

I have a table with several columns, between them I have one that is a SelectOneMenu, the table is loaded with a list of Inscricao.

In the status column of the application I have a SelectOneMenu with the status: {"Solicitada","Deferida","Indeferida"}. By default each registration when performed contains the status 0, ie "Requested", so I want to change the status of the registration in a listing when the user chooses an option other than the status that is currently in the registration.

The problem is I can’t get the Signup id and new value at the same time, so I can’t change the status value of the signup.

"i" is a variable that contains a list of entries:

<p:column headerText="StatusAdmin" filterBy="#{i.status}" filterMatchMode="contains" rendered="#{p:ifGranted('admin')}" >
    <p:selectOneMenu id="statusSelectOneMenu" value="#{i.status}" style="width:125px" 
            onchange="submit()" valueChangeListener="#{inscricaoBean.editarInscricao(i)}" >
        <f:selectItem itemLabel="Solicitada" itemValue="0" />
        <f:selectItem itemLabel="Deferida" itemValue="1" /> 
        <f:selectItem itemLabel="Indeferida" itemValue="2" />   
    </p:selectOneMenu>
</p:column>

In this way:

valueChangeListener="#{inscricaoBean.evt}"

I have access to the new value that was assigned, but in this case I do not know what the inscription related to this new value.

valueChangeListener="#{inscricaoBean.evt(i)}"

This way I have access to the inscription, but I do not know what the new value, as I do to have both at the same time?

Try the following:

Remove onchange="submit()" and valueChangeListener="#{inscricaoBean.editarInscricao(i)}"of your <p:selectOneMenu> and within it add:

<p:ajax event="change" process="@this" listener="{inscricaoBean.editarInscricao(i)}" />

Thus remaining:

<p:selectOneMenu id="statusSelectOneMenu" value="#{i.status}" style="width:125px">
                        <f:selectItem itemLabel="Solicitada" itemValue="0" />
                        <f:selectItem itemLabel="Deferida" itemValue="1" /> 
                        <f:selectItem itemLabel="Indeferida" itemValue="2" />   
                        <p:ajax event="change" process="@this" listener="{inscricaoBean.editarInscricao(i)}" />
 </p:selectOneMenu>

By adding this when you select a new option it will already process this value and set in its variable i and then you’ll call your method editarInscricao(), so it will have the new value.
