DataTable: Show Row When Provided With An Empty List
Hi all,
I've just started looking at JSF and to start I'm trying to throw together a little webmail application. At the moment I have the below simple DataTable. All works fine but I am wondering about one thing. When the user has no emails in their inbox, instead of just showing an empty table I would like to have a row that spans the total number of columns alerting the user that they have no email.Can anyone suggest an easy way to do this?
I can see that MyFaces' DataTable has a "renderIfBlank" attribute which I could use to hide the table and then create create a new blank table but this will mean duplicating a chunk of code.
So here's my code. As I touched on earlier - I'm using MyFaces so that's where the tags with a t prefix are from.
<t:dataTable id="yourmessages" rows="20"
var="message" value="#{userBean.folder.messages}"
rowIndexVar="rowIndex" width="700px">
<t:column width="30%">
<f:facet name="header">
<f:verbatim>
From
</f:verbatim>
</f:facet>
<t:outputText value="#{message.from}" />
</t:column>
<t:column width="40%">
<f:facet name="header">
<f:verbatim>
Subject
</f:verbatim>
</f:facet>
<t:outputText value="#{message.subject}" />
</t:column>
<t:column width="15%">
<f:facet name="header">
<f:verbatim>
Date
</f:verbatim>
</f:facet>
<t:outputText value="#{message.sentDate}" />
</t:column>
<t:column width="15%">
<f:facet name="header">
<f:verbatim>
Size
</f:verbatim>
</f:facet>
<t:outputText value="#{message.size}" />
</t:column>
</t:dataTable>
