Re: The "Presentation" Layer

I was trying out EXTjs, in conjunction with a trial of Valence from CNX.
There is way to a page at a time version. CNX has an example of how to do
paging. It is not in there demo videos, but is available with the free
trial. It was easy to use the code to make my own demo. I didn't get much
farther in my trial, The company decided to go a different direction in
web programming from the iSeries.

Re: [WEB400] The "Presentation" Layer



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.
