Tapestry leaks memory in IE. I'm using Tap 4.0.2. I did some research and
like to share it with you. The leaks may be more than I listed here as I did
not use client side validation on forms.
Tapestry form and DatePicker leak memory IE, here is what I did to remove
the leaks.
// the following code is to hack IE memory leaks.
if (typeof Calendar=="function") {
var tap_calendar_create=Calendar.prototype.create;
Calendar.prototype.create=function() {
tap_calendar_create.call(this);
dojo.event.browser.addClobberNodeAttrs
(this._previousMonth,["onclick"]);
dojo.event.browser.addClobberNodeAttrs(this._nextMonth,["onclick"]);
dojo.event.browser.addClobberNodeAttrs
(this._todayButton,["onclick"]);
dojo.event.browser.addClobberNodeAttrs
(this._clearButton,["onclick"]);
dojo.event.browser.addClobberNodeAttrs
(this._calDiv,["onselectstart","onkeydown","onmousewheel"]);
dojo.event.browser.addClobberNodeAttrs(this._table,["onclick"]);
dojo.event.browser.addClobberNodeAttrs
(this._monthSelect,["onchange","onclick"]);
dojo.event.browser.addClobberNodeAttrs
(this._yearSelect,["onchange"]);
return this._calDiv;
};
}
if (typeof Tapestry=="object") {
Tapestry.register_form = function(formId)
{
var form = this.find(formId);
form.events = new FormEventManager(form);
dojo.event.browser.addClobberNodeAttrs
(form,["events","onsubmit","onreset"]);
};
}
