h:CommandButton action problem

bkasodariya Aug 27, 2011 10:27 AM

Hi,

I have created one simple master page. There is cancel button with action in that page.To execute action, I have to press cancel button two times.
Why its not working on single click.

Here is my jsf page

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"

xmlns:h="http://java.sun.com/jsf/html"

xmlns:a4j="http://richfaces.org/a4j"

xmlns:rich="http://richfaces.org/rich"

xmlns:f="http://java.sun.com/jsf/core"

xmlns:ui="http://java.sun.com/jsf/facelets">

<h:head></h:head>

<h:body>

<h:form id="productMasterForm">

<rich:panel>

<f:facet name="header">

Product Master

</f:facet>

<h:panelGrid columns="2">

<h:outputLabel value="EAN" />

<h:inputText value="#{productMaster.ean}"

readonly="#{productMaster.editMode}" />

<h:outputLabel value="Product Descirption" />

<h:inputText value="#{productMaster.productDesc}" />

</h:panelGrid>

<a4j:commandButton id="save" value="Save"

action="#{productMaster.addProduct}">

</a4j:commandButton>

<h:commandButton id="cancel" value="Cancel"

action="/pages/ProductList.xhtml">

</h:commandButton>

<h:message showSummary="true" showDetail="false"

style="color: red; font-weight: bold;" for="save" />

</rich:panel>

</h:form>

</h:body>

</html>

hello,

In your page, the form is a h:form.
is this something you really want ?

you should use a : a4j:form
this should resolve this kind of double click problem.

also, your first command button is a : a4j:commandButton
the second one (cancel), is a h:commandButton

I guess you made the h:commandButton to be able to go to the "/pages/ProductList.xhtml" that is outside of the JSF application (in "another" jsf application, in another war, or so...) ?

the more simple use case is to use some a4j:commandButton, for ajax request, in the same JSF application.

for other use case, you might want to look at and use the richfaces htmlCommandLink.

hope it helps.

Thanks for your response Antonie,

I tried to use a4j:form but its giving tag error at runtime. I am using richfaces 4.0

I am navigation in same jsf application.If i use a4j:commandbutton then i have to click two times.For h:commandbutton its working fine.

Thanks.

Hi,

Use h:CommandButton and make sure its inside <h:form>

Thanks,
