[Seaside] With several JQDialog ... it gets very slow!

ha yes, this is where you need to start using delegated events.

Take a look at http://api.jquery.com/on/

I have to head out the door now, but I can come back with a more elaborate answer. The basic idea is:
- catch the click event on the table (not on the cell)
- generate (and open) the dialog in an ajax request when catching the click
- you can (manually) lookup the passenger of the cell from it's id.

If you have not figured it out by later tonight (my time), I will get back to you ;-)

With a table of around 250 items and 3 or 4 columns with popups..that is ... 1000 JQDialog instances at render time, it gets very slow! The table passes from 1s to render to 3s! :(
