Re: The "Presentation" Layer

Hi Aarron,

There is an excellent paging grid with page by page presentation, remote
sort on the server, and even the option to create extra parameters for the
remote Ajax call, for example specifying a "where" statement for an SQL
call. This is ideal for SQLRPGLE on the server.

Just to comment on things like the ExtJS grid...

... the thing that drives me nuts the most is that out of the box most of
these grid controls don't promote the use of paging. For example, if you
have 100,000 records in a file then the user should only be returned the
actual number of records they are viewing (or you could buffer a page before
and a page after if you wanted to).

What type of paging capabilities does Ext JS provide to "go back to the
well" for the next pages worth of data vs. loading the entire dataset in the
browser all at once?

The page comes up and I see a grid, but nothing in the grid.
Is this correct?

Hmmm, I don't know what happened. Maybe the result set was too large for
my slow modem. I don't know. I changed the cursor filter to generate a
smaller result set. Try again. Be patient for the response. This is my
first attempt at communicating with an Ext JS client.

Regarding losing the ability to bookmark a rich-client interface, that's
fine for the type of applications I deploy, but the point is well taken.

Nathan.
