Thanks Martin for the response. Could you please answer the below question as

What is the use of the below API?

Does it make any difference to the render strategy? I guess it makes some
difference to 'REDIRECT_TO_BUFFER'.
Thanks,
Yes it is. Thanks

call to my service wrapper asking for all the entries. For example: if total

different from using list view. How can I make sure that this data view
loads
Thanks Igor for the response.
If I use dataview.setItemsPerPage(50), then my Data View loads only the
first 50 entries. But how can I trigger or ask the data view to load the

list?

thanks for the info Dan.
I haven't worked with Jquery before. I will explore more on that. But I am
curious to know why DataView stores information in the session. Because I
use LoadableDetachableModel in my above example. The main objective for me
is minimize the information stored in session.

Am I missing something?
Ya, I just noticed some issues if I setRenderBodyOnly(true) to all the

properly. For now I think I will go through each component and then decide
whether they need markups or not.
