[Seaside] Trigger a method from javascript

[Pierre Durand]

Hi

I have a nice UI using Pharo/Seaside ans I’m able to control the program flow with AJAX callbacks on the UI but only when there are user actions.
The are some asynchronous processes in javascript (server connexion, file downloads) and I would like to trigger some methods in the pharo code when they complete.
What are the options ? Do i have to trigger some event ? How do I read/listen to them ?

Thanks !

Pierre
