My Datatable missing rows

[liyer]

Hi All,
I'm having problems with datatable, scrollableDataTable, extendedDataTable... so eventually, I'm trying to display a static datatable and all rows are missing. What's going on? Help!!
Thanks
Lak

Here is my code:
<ui:composition template="/WEB-INF/template/common.htm"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:jdsu="http://jdsu.com/jsf"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:s="http://jboss.com/products/seam/taglib"
xmlns:rich="http://richfaces.org/rich"
xmlns:c="http://java.sun.com/jstl/core"
xmlns:a4j="http://richfaces.org/a4j">
<ui:define name="pageParameters"></ui:define>
<ui:define name="contentRightColumn">
<h:form id="myform">
<rich:panel id="mypanel">
<rich:dataTable id="mydatatbl" width="500">
<f:facet name="header">abc</f:facet>
<rich:column id="one"><h:outputText value="def" /></rich:column>
<rich:column id="two"><h:outputText value="def" /></rich:column>
<rich:column id="three"><h:outputText value="def" /></rich:column>
<rich:column id="four"><h:outputText value="def" /></rich:column>
</rich:dataTable>
</rich:panel>
</h:form>
</ui:define>
</ui:composition>

datatable, scrollableDataTable, extendedDataTable are iterators. Nothing to iterate, nothing is displayed.

Hi Lak, just put in var and value attributes, provide an empty list and everything should work

Have a look at the following example, if you don't know how:

This is the code that led me to strip all variables and make it static. This doesn't display any rows either!! There is a lot of data actually, I can see it when I change datatable to dataGrid. But I need the dataTable.
Hits is <List <List < String > >.
Please, help!

Hello,

This won't work. rich:columns documentation contains a special note about this case: http://www.jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/html/columns.html

I was not getting any kind of exception with the above code.

I'm not sure how the c:forEach would give me a dataTable. Anyways, I tried replacing the dataTable with forEach and got a ServletException.

Thank your for all your responses. My problem is still not resolved. Are there any workarounds for this?

Try value="#{bean.columns}" where bean.columns is a predefined collection of columns, e.g. ["Column1", "Column2", "Column3", etc.]. Also you can take a look at the livedemo example.
