Move from tab A -> tab B, data in tab A reloaded?

[dxxvi]

I use a rich:tabPanel having 3 rich:tab inside. The rich:tabPanel and rich:tab have the attribute switchType of `ajax'. In each rich:tab I have a rich:dataTable like this:

<rich:dataTable id="dataTableA" var="pl" value="#{adminBackingBean.allAs}">
 <f:facet name="header">
 <rich:columnGroup>
 <rich:column><h:outputText value="ID"/></rich:column>
 <rich:column><h:outputText value="Programming Language"/></rich:column>
 </rich:columnGroup>
 </f:facet>
 <rich:column><h:outputText value="#{pl.id}"/></rich:column>
 <rich:column><h:outputText value="#{pl.value}"/></rich:column>
</rich:dataTable>

Data in 3 tabs are from 3 different database tables.

When I'm in tab A and click on tab B, in the log file, there's a sql statement which retrieves the data for tab A from the database, and of course there's a sql statement which retrieves the data for tab B. So, does the current tab have to be reloaded when we move to a new tab? Or am I doing something wrong?

Do you initiate the access to the database in the manager bean property getter (i.e. inside the getAllAs() )?

Yes, I do. If it's a wrong way, please tell me other ways. Thank you very much.

It seems to me that the rich:dataTable is only reloaded when it's not in a form (in each rich:tab, I have a form which contains the rich:dataTable and the data in the rich:dataTable isn't reloaded when I move between tabs).

So, what does RichFaces do internally?
