Rails - Jul 2005 - Ajax from a pop-up

Heya,

I''m trying to start an ajax call _for_ the underlying "main"
window from
a pop-up, but it doesn''t work. Firefox throws a strange error message:

Error: [Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]"  nsresult:
"0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame ::
http://localhost/javascripts/prototype.js :: anonymous :: line 190"
data: no]
Source File: http://localhost/javascripts/prototype.js
Line: 190

I defined a javascript function (add_associated) in the main window
which basically does the Ajax.Updater. This function gets called by the
popup with:

window.opener.add_associated(''param'', ''url'')

It all works fine if I remove the self.close() after the function call
in the pop-up!

What I''m trying to do is a element chooser for a belongs_to/has_many
association with hundreds of elements (so a simple drop down doesn''t
work here).

Any ideas how I can make this work?

Or better, how the pop-up can give me a return value which the main
window uses for an ajax call right after the pop-up is closed?

Or even better, show me an ingenious alternative to solve this GUI
problem :)

thanks a lot
Florian

Okay,

I got it working with the following workaround:

in the pop-up:
window.opener.focus()

hides the pop-up

in the main window I put

newwin.close() in the onComplete: part of the Ajax.Updater

so this works for my case, but I''m still curious why the Ajax.Updater
doesn''t work if I close the pop-up too early.


thanks,
