Hi Isaac,
What I want to know is,
1) Where and how does the data actually get loaded into the table.
Where is the call that does this? Looking through the PagingScrollDemo
code I can't seem to isolate that point from where the data is
retrieved remotely and loaded up into a table. i.e what call triggers
this action from the PagingScrollTableDemo to finally obtain the data
and which point in the whole process does it happen. In the case of
the ScrollTableDemo I see that the onModuleLoaded() method is called
which seems to be responsible for initializing the data. I was able to
get the same successfully compiled using my own example, but now when
trying to understand the PagingScrollTableDemo, I am getting lost as
to what call is specifically to begin the data retrieval and loading
into the table.
Thanks for the patience.
Suri
