Hi,
I have a simple example in Rails 2.1.2, 2.2.2 using the auto_complete
plugin. It works wonderfully. However, I was wondering how it would
handle errors. For example, if for some reason a person couldn''t be
found, the HTTP request will come back with a 404
def auto_complete_for_people_foo
# Cause a deliberate error
people = Person.find(22222) # doesn''t exist
. . .
end
Or there might be a syntax error in the code and we get a 500 error
back.
def auto_complete_for_people_foo
# Cause a deliberate error
asflksajflasjlf # Not valid Ruby code
. . .
end
For other AJAX functionality in our application (e.g. form_remote_tag)
we have global AJAX repsonders as follows:
Ajax.Responders.register({
onComplete: function(transport) {
console.info("COMPLETE");
Element.hide(''spinner'');
if (transport.transport.status == 0 || transport.transport.status =12029) {
// Lost connection as reported in Firefox (0) or IE (12029)
alert("The connection with the server has been lost.");
console.info("LOST CONNECTION");
} else if (transport.transport.status != 200 ) {
alert(String.format("The server has reported an error with code
{0}", transport.transport.status));
console.info("ERROR");
}
},
onCreate: function() {
Element.show(''spinner'');
console.info("LOADING...");
}
});
For auto_complete, the onCreate callback gets invoked, but the
onComplete one never does. I''ve checked this in Firebug - I can see
the 404 or 500 POST errors, but I the
Does anyone have any ideas or areas they can point me to?
TIA
Cam.

The last bit should have read: For auto_complete, the onCreate callback gets invoked, but the onComplete one never does. I''ve checked this in Firebug - I can see the 404 or 500 POST errors, but the onComplete responder never kicks in.

When I CTRL-F5 to start off afresh, the Ajax.activeRequestCount is 0. If I type in my name very slowly into the edit box, the count is now 7 - it is never decremented. When my code is running normally (i.e. I''m not deliberately forcing errors), the count always returns to zero.

Strangely enough when the focus is on the auto complete edit field in Firefox and I ALT-TAB to my editor, another AJAX request is made, but this time the onComplete gets called and I get the alert message box On Nov 28, 10:21 am, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On Nov 28, 10:16 am, Cameron McCloud <cameron.mccl...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> > wrote:> When I CTRL-F5 to start off afresh, the Ajax.activeRequestCount is 0. > > > If I type in my name very slowly into the edit box, the count is now 7 > > - it is never decremented.

I put a breakpoint on dispatchException and it hits that with the following: TypeError: element.hasClassName is not a function message=element.hasClassName is not a function. The line that triggered the exception is in prototype.js line 1322 (Latest Prototype.js 1.6.0.3) However, I also get this even if I don''t have any Ajax responders set up.

On reading the Prototype docs (something I should have done earlier), there''s another Responder for handling exceptions - onException. This does get called and through it I can let the user know that something went wrong. It doesn''t seem to tell me if the problem is a 404, 500 and I can''t tell if the server is no longer available, but it''s a start. Thanks for all your help Frederick. Cameron.
