simple application with one grid(126 Mb of RAM):

I've destroyed the grid, but save the reference of grid.view into variable a,
created new property "f", and added many dom-elements into...

hm,
very interesting, because for me this problem has gone after upgrading to 4.1.1

[by rsqw]

this has been fixed in extjs4.1.1

I can't agree with you, it's Extjs issue, because "very slow grid scrolling" appears only in infinite-grids, just try simple grid-examples from sencha-documentation <-- they work

[by rsqw]

Any news about this bug?

[by rsqw]

Same issue, Archlinux

hm, there is no "useComponent" in src-path of the framework :((

[by rsqw]

nice thoughts

[by rsqw]

Scott, thanks for your explanation.

Unfortunately I cannot find documentation for this, where I can read about useComponent?

owenho, it's just a UTF-8 encoding, where is the problem?

[by rsqw]

Hi,

My question is quite simple:
Buffered-Store caches the models into PageMap, and as a result store contains deprecated data (because Store doesn't make an Ajax-request for fresh portion of...

Ok, I'll try to make things clear.


Ext.define("Website", {
extend: "Ext.data.Model",
idProperty: "websiteId",
fields: [
'websiteId',
'website',

The private function destroyStore() in 4.x should do what you need --- unfortunately, no :(

in my case after user.posts().destroyStore(), user.postsStore still exists :(

[by rsqw]

Scott, Thank you for fast response,

Yes storeId helps,
BUT not in case with buffered-grid :(,

In my application I've a buffered-grid:


Ext.define("grid", {
extend:...

Hi,

How can I completely destroy the associated store?

My solution is:


user.posts().destroyStore();
delete user.postsStore;

[by rsqw]

Hi,

I've just noticed, that Ext.StoreManager doesn't register associated-stores, does anybody know how to fix this?

Thanks!!!

Hi,

I cannot find any solution to removeEventListener, when I use relayEvents:


var panel = Ext.create("Ext.Panel", {
title: "Panel",
items: [{
xtype: "button", text: "Button1"
}]

[by rsqw]

chrome faster because of V8
