How can I prevent p:commandButton to refresh p:tabView

Question

my xhtml page has this format:

    <h:form>
      <p:dialog widgetVar="presentDiag" modal="true" closable="true" header="Liste" maximizable="false" dynamic="true">

            <p:commandButton value="Submit" id="submit" actionListener="bean.add()"/>
      </p:dialog>
    </h:form>
    <h:form>
       <p:tabView>
            <p:tab title="....">
            </p:tab>
            <p:tab title="....">
            </p:tab>
            <p:tab title="....">
           </p:tab>
           </p:tabView>
       </h:form>

when I click on the submit button the selected tab changed to the first tab

If you wanted to update a form and then exclude something from it, the easiest way would be to use PrimeFaces selectors like so :

<h:form id="form">
  <p:dialog widgetVar="presentDiag" modal="true" closable="true" header="Liste" maximizable="false" dynamic="true">
        <p:commandButton value="Submit" id="submit" actionListener="bean.add()" update="@(form :not(.tab-view))"/>
  </p:dialog>
  <h:panelGroup styleClass="tab-view" >
       <p:tabView>
           <p:tab title="....">
           </p:tab>
           <p:tab title="....">
           </p:tab>
           <p:tab title="....">
           </p:tab>
       </p:tabView>
   </h:panelGroup>
 </h:form>

you can always reopen a desired tab by using widgetVar attribute.

<p:tabView widgetVar="myTab"> .... </p:tabView>
 .
 .
 .
 <p:commandButton value="Submit" id="submit" actionListener="bean.add()" update="someId" oncomplete="myTab.select(2);"/>

but the best thing to do would be not closing it in the first place.
