操作完成后，JSF 2页面未刷新

Question

I'm having an issue where my page is not refreshing after an action completes.

I have this form on a page:

<h:form id="fundingResults">

    <p:ajaxStatus style="width:16px;height:16px;">
        <f:facet name="start">
            <p:graphicImage value="/images/loading4.gif" />
        </f:facet>
        <f:facet name="complete">
            <h:outputText value="" />
        </f:facet>
    </p:ajaxStatus>

    <p:dataTable>
        // some form elements in the table
    </p:dataTable>  

   <p:commandButton id="btnEdit" value="Submit" type="submit" action="#{fundingBacker.classifyProducts}" style="float: right;margin-top:15px;" />           

</h:form>

My classifyProducts method skeleton is like this:

public void classifyProducts() {
    // a bunch of stuff goes on in here
}

Shouldn't the page refresh automatically after the classifyProducts() method completes because of implicit naviation?

Answer 1

Primefaces command buttons send ajax requests by default. Try to add attribute ajax='false' to p:commandButton .

Answer 2

You need to specify what parts of the page to refresh. For example adding update="@form" to the commandbutton tag should to the trick here, or you could specify the id of the individual components to update.
