Description

In the example below, a method `testView.getList()` is called every time the button is pressed. I think this is not expected behavior.

 

<h:form id="frmTest">
    <p:commandButton value="button" styleClass="alt-btn" action="#{testView.onSubmit()}" process="@form" partialSubmit="true" update=":updatetestpanel"/>
</h:form>

<h:panelGroup id="updatetestpanel">
    Some text
</h:panelGroup>

<ui:repeat value="#{testView.list}" var="val">
    <h:outputText value="#{val}"/>
</ui:repeat>

 

I checked with MyFaces 2.2, MyFaces 2.3, MyFaces 2.3-next-M2 (which we currently use), and Mojarra 2.3, and only the last one doesn't have that issue.
