[grid-component] javascript style for ordering rows

[manuel aldana <al...@gmx.de>]

I really like the grid component. Especially the built-in ordering 
(clicking on column headers).

what I miss is that javascript is not used when ordering the tables, at 
each click a complete HTTP request is fired. The data itself is not 
changed so another server call wouldn't be necessary. I at least did not 
find a javascript enable parameter.

If it is not supported yet, maybe this could be a nice improvement for 
this component. For non-JS clients maybe there could even be a fallback 
to standard HTTP request style.

Apart from that why was grid-component not desinged to use div-style 
(vs. tables) for row layout? maybe due to browser compability 
(especially older IEs)?

Nested <divs> for layout is one thing, and has been distorted in the
past for a non-rectangular layout.

The Grid is displaying ordered rows and columns: what could be more
natural than a <table>?

Yes, in my first thread post I overlooked the pagination problem.
Thanks for the 'inPlace' parameter hint.

Yes, but I wonder why it does not use div-style.

You're not exactly right. When Grid has more rows to show than rows
per page, you cannot just reorder the objects that are being shown,
you must reorder the whole row list. By the way, don't forget the
inplace="true" Grid parameter: it reorders the Grid using AJAX.

I'm not following you: it does use a table.

OK, maybe I see the reason for firing the request another time. It is 
about the pagination if my list result (many entries) spans several 
pages -> it is far from obvious to let javascript know how to order this...
