I tried with the options @form,: matricula, matricula_form ... and nothing.
When I delete the bank registration, only after updating the page does it disappear, I'm forgetting something ???
Follow the code "enrollment_list" below
<!DOCTYPE html>
<p:commandButton value="Nova Matricula"
action="#{matriculaBean.novaMatricula}" update="matricula_form"
icon="novo-icon" />
<p:dataTable value="#{matriculaBean.matriculas}" var="matricula"
style="margin-top:10px; width:100%" emptyMessage="Nenhuma matrícula cadastrada">
<p:column headerText="Número" width="40" style="text-align:center;">
<h:outputText value="#{matricula.numero}" />
</p:column>
