Update JSF datatable without refreshing the page - jsf

Question

I have input fields and datatable in the same page, in such a way that when user adds a new data, data should be added to the datatable without refreshing the page.
To achieve this I tried the following code
xhtml part
<table border="0">
<tr>
<td width="700" height="100px">Customer Name: <h:inputText
immediate="true" id="customername" autocomplete="false" value="#{salesBean.customerName}">
</h:inputText>
</td>
</tr>
<tr>
<td width="900" height="160px">
<table border="1">
<tr>
<td align="left">Product Name</td>
<td align="left">Rate</td>
<td align="left">Quantity</td>
<td align="left">Total Price</td>
<td align="left">Paid</td>
<td align="left">Date of Sales</td>
<td align="left"></td>
</tr>
<tr>
<td align="left"><h:inputText immediate="true"
id="productname" autocomplete="false" value="#{salesBean.productName}">
</h:inputText></td>
<td align="left"><h:outputText id="rate"
binding="#{salesBean.productRate}" /></td>
<td align="left"><h:inputText size="2"
onkeyup="return calculateTotalRate(event);" id="quantity" value="#{salesBean.quantity}"/></td>
<td align="left"><h:outputText id="totalprice" /></td>
<td align="left"><h:selectOneRadio id="sor"
title="Select any one of the choice" value="#{salesBean.paidFlag}">
<f:selectItem id="si1" itemLabel="Yes" itemValue="yes" />
<f:selectItem id="si2" itemLabel="No" itemValue="no" />
</h:selectOneRadio></td>
<td align="left"><rich:calendar id="salesDate" value="#{salesBean.salesDate}"></rich:calendar></td>
<td align="center">
<h:commandButton value="Submit">
<a4j:support action="#{salesBean.submit}" reRender="table"></a4j:support>
</h:commandButton>
<h:commandButton value="Cancel" /></td>
</tr>
</table>`
</td>
</tr>
<tr>
<td>
<h:outputText id="errormessage" style="display:inline-block;color:Red;width:300px;"/>
</td>
</tr>
<tr>
<td>
<h:panelGroup id="panel">
<rich:dataTable var="data" id="table" binding="#{salesBean.table}" rendered="#{salesBean.salesHistoryRendered}">
<h:column>
<f:facet name="header">
<h:outputText value="Product Name"/>
</f:facet>
<h:outputText value="#{data.productName}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Date of Sale"/>
</f:facet>
<h:outputText value="#{data.dateOfSales}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Is Paid?"/>
</f:facet>
<h:outputText value="#{data.paidCheck}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Quantity?"/>
</f:facet>
<h:outputText value="#{data.quantity}"/>
</h:column>
</rich:dataTable>
<h:outputText id="text" binding="#{salesBean.checkValueChangeListener}"/>
</h:panelGroup>
</td>
</tr>
<tr>
<td>
</td>
</tr>
</table>
Please help me to solve this. Please update me if my question is not clear.
I am using JSF 1.2 and Richfaces 3.3.2
Thanks in advance

Answer 1

You have missed event attribute in a4j:support. Should be like this (disableDefault="true" is to prevent h:commandButton standard behavior):
<h:commandButton value="Submit">
<a4j:support event="onclick" disableDefault="true" action="#{salesBean.submit}" reRender="table"/>
</h:commandButton>
Or even better like this (will do the same as the lines above, but in more a4j-style):
<a4j:commandButton value="Submit" action="#{salesBean.submit}" reRender="table"/>

Answer 2

"Without refreshing the page" means AJAX.
RichFaces 3.3 has AJAX support, and their documentation explains how to use it in chapters 5.1 through 5.7.
