[Seaside] immediate display alert to user while Ajax request

[jtuchel at objektfabrik.de]

Sabine,

fur such things, I set up an instance  variable in the component with 
the text to display, for off a process that does the actual processing 
and updates the variable with the text reperesenting the progress.

On the client side, I setup a timeout that will issue an ajax callback 
back to the server every x smsecs and. The server will answer the 
current string. The Javascript code can then update the "please wait" 
dialog, or, in your case, open an alert if the text has changed from 
last time.

I am not near an image right now, so I cannot provide sample code...

Joachim
