每个ajax请求上的JSF更新组件

Question

Hi i want to render the JSF messages as bootstrap alerts

<ui:repeat value="#{facesContext.messageList}" var="facesMessage">
    <div class="alert">
        <button type="button" class="close" data-dismiss="alert">&times;</button>
        <strong>Warning!</strong> #{facesMessage.summary}
    </div>
</ui:repeat>

in primefaces there is

<p:messages autoUpdate=true>

means it is rerendered on every ajax request without explicit adding it to the render-attribute of a commandLink

is there a way to achieve this with plain JSF-ajax tags?

Answer 1

You might try something like this during your page load:

jsf.ajax.addOnEvent(autoRender);

And in autoRender you would be able to trigger a kind of action in order to render the target component. For instance:

function autoRender() {
    $(":form:autoRenderHiddenButton").click();
}

And in the button:

<h:commandButton id="autoRenderHiddenButton" 
                 style="display: none">

    <f:ajax render="theComponentIdYouWantToRender"/>
</h:commandButton>

Or you can easily achieve the same behavior by using Omniface's commandScript :

<o:commandScript name="autoRender" render="theComponentIdYouWantToRender"/>
