I may have something now that keeps IE from hanging on a page refresh.
Here's what I've changed in the 0.9.31 JS code:
------------------ Nevow/Athena/__init__.js (2 additions)
--------------------------
Nevow.Athena.Widget._initialize = function() {
Divmod.debug("widget", "Instantiating live widgets");
Nevow.Athena.Widget._pageLoaded = true;
// With the next line, sendCloseMessage will get called in IE. // Harald
Divmod.Base.addUnLoadEvent(Nevow.Athena.page.deliveryChannel); // Harald
Nevow.Athena.Widget._instantiateWidgets();
Divmod.debug("widget", "Finished instantiating live widgets");
};
Nevow.Athena.bootstrap = function (pageClassName, clientID) {
var self = this;
var pageClass = Divmod.namedAny(pageClassName);
self.page = pageClass(clientID, Nevow.Athena._createMessageDelivery);
Nevow.Athena.page = self.page; // Harald
self.page.bindEvents(window);
.....
------------------ Divmod/Base.js (1 added function at the end)
--------------------------
Divmod.Base.addUnLoadEvent = function(channel) {
/***
Harald's desperate try to get IE page refresh to work...
***/
window.attachEvent("onunload", function (e)
{channel.sendCloseMessage();});
};
Divmod.Base.jsonRegistry = Divmod.Base.AdapterRegistry();
I'm not used to this coding style, so it's a bit of trial & error. Anyway,
before, sendCloseMessage would _not_ be called; now it is, and I can refresh
ad lib on IE 6.and 7.
Not sure either what this will do to FF. (Since we're stuck with IE, I'm
heavily abusing its non-standard extras, so I can't get my full app to run
on FF.) Besides, you're better on FF than I am :-)
Finally, to fix the onkeypress issue, I think we'd need to go deeper into
the "this" dept. For me, the refresh is more important - if the users insist
on pressing ESC, they can blame themselves.. ;-)
What do you think?
Regards,
Harald
