How to use datatable with no records in a list

[Priti Shah]

Hi ,

I have a datatable which displays 4 columns. Each column has a header. I use arraylist with datatable.

Here is what i want to do. When arraylist has values then datable works fine but when arraylist is null or has size 0 I still want to display column headers and a single row dispalying message "No record found".

I did following for this.

First I added this

<h:datatable...   rendered="#{!empty myBean.list}"/> 
<h:column>
<f:facet name="header">
<h:outputText value="#{message['v.common.numbersign']}"/>
</f:facet>
<h:outputText value="#{myBean.index}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{message['name']}"/>
</f:facet>
<h:outputText value="#{myBean.name}" />
</h:column>

So this will not renderer my datatable at all if list is null.

Now I add another datatable tag with

<h:datatable...   rendered="#{empty myBean.list}"/> 
<h:column>
<f:facet name="header">
<h:outputText value="#{message['v.common.numbersign']}"/>
</f:facet>
<h:outputText value="#{myBean.noRecFound}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="#{message['name']}"/>
</f:facet>
<h:outputText value="#{myBean.name}" />
</h:column>

This data table will only show headers and a 'no rec found' message. But this will show message in the first column only. I want to display it as one row without any columns.(In HTML terms I want to assign colSpan=4 to display it as a row)

If any one can suggest any thing.

Thanks in advance.

I edited your post to use Code Tags and I also removed the smilies. In the future try to use code tags when posting code and especially when posting JSP tags and such disable smilies in the post. There is a checkbox towards the bottom of the new post form.

Customize the data table renderer.

Couldn't you use PanelGrid with PanelGroup in the #{empty myBean.list} case? See PanelGrid example: http://www.exadel.com/tutorial/jsf/jsftags-guide.html
