Problem in <rich:dataTable>

[dev aaa]

I am using Rich data Table to display list of urls.
The user has an option to delete or edit a url.

<rich:dataTable
onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
cellpadding="0" cellspacing="0"
width="550" border="0" value="#{CreateViewBean.urlList}" var="urlList1" rendered="#{CreateViewBean.displayTableData}" binding="#{CreateViewBean.dataTable}">
<f:facet name="header">
<rich:columnGroup>
<rich:column >
<h:outputText value="URL" />
</rich:column>
<rich:column>
<h:outputText value="Actions" />
</rich:column>
</rich:columnGroup>
</f:facet>
<rich:columnGroup>
<rich:column styleClass="style9"><h:outputText value="#{urlList1}" ></h:outputText></rich:column>
<rich:column>
<h:graphicImage value="../images/tab_actions_edit.gif" alt="Edit" /> <h:commandLink action="#{CreateViewBean.removeURL}"><h:graphicImage value="../images/tab_actions_delete.gif" alt="Delete" /> </h:commandLink> </rich:column>
</rich:columnGroup>
</rich:dataTable>

The problem that I am facing is when the user clicks on the Delete button nothing happens.

The java code is as follows:

public void removeURL(){

String urlRemove = (String)getDataTable().getRowData();
System.out.println(urlRemove);
}

public boolean isDisplayTable() {
if(urlList.size()>0)
{
displayTableData = true;
}
return displayTableData;
}

Please let me know, what mistake I am doing.
Thanks in advance

Can we use rendered and binding both properties of dataTable together?

As in the above case if I remove any one property of dataTable it works fine.

In my application I do not want to show the table if row count is less than one.

In my application I do not want to show the table if row count is less than one.

Try this:
rendered="#{CreateViewBean.urlList.rowCount!=0}">

may be need <h:form>

Thanks for your help but
rendered="#{CreateViewBean.urlList.rowCount!=0}"
does not work.

However I was able to solve the problem by using rendered property in
column group instead of dataTable
<rich:columnGroup rendered="#{CATCmaCreateViewBean.displayTable}">
