View Full Version : [UNKNOWN][3.1] Page content disappears in FF after upgrade to 3.1

30 Dec 2009, 11:10 AM
This is a blocker for us. The content of many of pages disappears in FF, after upgrade from 3.0 to 3.1. Works fine in IE.

I can't yet pinpoint the problem, but it seems related to multi-column forms (form layout under table layout) plus a few other minor factors.

Here's a much simplified page that can reproduce the problem. It looks fine in IE, but none of the textfield shows up in FF:

<script type="text/javascript">
Ext.onReady(function() {
var twoCols = {
layout: 'table',
layoutConfig: {'columns': 2},
defaults: {layout:'form', border:false, defaultType:'textfield'},
items: [
{ fieldLabel: 'First Name', value: 'John' },
{ fieldLabel: 'Last Name', value: 'Smith' }

items: { fieldLabel: 'Info' }

new Ext.Viewport({
layout: 'anchor',
{ html:'blah' }

Try setting forceLayout:true of your twoCols literal.

Thanks, Eugene! forceLayout:true is a good workaround. (However, because this form is not under a hidden or collapsed container, this flag should not be needed. So still a bug.)

I also found another workaround, to just remove border:false from the form config. (But why??)

Could someone explain the FF behavior change in 3.1, so we can understand the impact of this change (or bug)? Thanks!

This is a known bug in the Ext 3.1 TableLayout (see here (http://www.extjs.com/forum/showthread.php?p=420133#post420133)).

ps. You should add an anchor to the twoCols panel to set the width, e.g.

anchor: '100%'

Thx Condor.

The fix in Container.canLayout() does the trick. Looking forward to the official fix.

Right, anchor:'100%' got lost when I tried to simply the test case.
