log4dataTable

[Dennis Byrne <de...@dbyrne.net>]

In JSP:

 <h:dataTable id="foo" var="item" value="#
{CommitteeLister.list}" >
 </h:dataTable>

I get the following logging output.  If I remove the 
dataTable from the JSP, this message goes away.  Notice the 
dataTable has an id.

Why is something with "WARNING" being piped down the INFO 
channel?

INFO  org.apache.catalina.core.ContainerBase.[Catalina].
[localhost].[/hbm2jsf] - WARNING: Component _id13 just got an 
a
utomatic id, because there was no id assigned yet. If this 
component was created dynamically (i.e. not by a JSP tag) yo
u should assign it an explicit static id or assign it the id 
you get from the createUniqueId from the current UIViewRoo
t component right after creation!

The datatable needs the id of the parent component to work if it is 
nested in an other datatable.

You get the warning because the parent component doesn´t have an initial 
id so it is generated automatically. If the parent is f:view you can 
ignore this warning or put the datatable inside of a h:panelgroup 
component to get rid of the message.
