Seam and JSF EL Expression

what's the difference about the two examples bellow (and benefits of one versus another)? How do I choose one or another?

<rich:dataTable id="..." value="#{someService.messageList}" ...>
...
</rich:dataTable>

and

<rich:dataTable id="..." value="#{messageList}" ...>
...
</rich:dataTable>

The first one will get the instance of messageList from someService component

The second one will get the messageList that is created by the @Factory

I prefer using the second one since sometimes I need to get the rowCount from the messageList but the first one is good also. It's a matter of preference and your coding style

but it's not necessary to use any factory method to get it to work...

Is it about dependency injection?
