View Full Version : ExtJS.com Login Screen

24 May 2010, 9:01 AM
I use Ext JS 3.2.0 version

When I do refresh with one of the screen developed using Ext JS, its showing a popup to login extJS.com

I have attached the screen. it's not showing up all the time. It's showing up some time and very rarely and for some developers only. I still didn't get exact flow in which this login screen popup.

I do get this screan recently when I upgraded from ext JS 3.1.1 to 3.2.0. Is something else I need to do or missing to avoid this screen?

Does anybody got this type screen.

Have you looked at firebug to see what requests are going there? Where is your BLANK_IMAGE_URL ref pointing?

Have you set?

Ext.BLANK_IMAGE_URL = '../My/Path/To/Image/blank.gif';

View the docs (http://www.extjs.com/deploy/dev/docs/?class=Ext) for more info on this.

Excerpt: URL to a 1x1 transparent gif image used by Ext to create inline icons with CSS background images. In older versions of IE, this defaults to "http://extjs.com/s.gif" and you should change this to a URL on your server. For other browsers it uses an inline data URL.

There was another thread in the forum discussing this.

I was testing in IE and couldn't find firebug to see the request. I will keep you updated if I get same when I try in Firefox.

I think this is related to Ext.BLANK_IMAGE_URL.

I do see in IE bottom progress bar that "Downloading Picture http://extjs.com/s.gif". I have attached that portion also now.

Is this solve, if I add below line?


What is the alternative location of image I need to provide instead of "s.gif" ? What is this GIF file all about?

I have added now with following code, Let me see if I get the login screen again.
Ext.BLANK_IMAGE_URL = '/extjs320/resources/images/default/s.gif';

Just point it to location of s.gif on your server. In my case it is

Ext.BLANK_IMAGE_URL = './ext/resources/images/default/s.gif';

I have tried with Ext.BLANK_IMAGE_URL = '/extjs320/resources/images/default/s.gif'; and Ext.BLANK_IMAGE_URL = '';

Both are working and login screen doesn't appear. But the UI is not rendering properly, if I add above code.

Please look at my ComboBox "V" image getting scattered and not displaying properly. Same thing happens to date Picker as well.

I have attached before and after images of the combo.

Can anybody tell whats the exact fix for this issue? This seems if we overwrite Ext.BLANK_IMAGE_URL from Extjs.com location, it wont render properly.
