Column-Header moves when resizing Column-Width

[jonas007]

In Ext JS 4.1.1 there is a strange behavior. Look at the small example below.
When I open the window, I scroll the grid to the right.
Now I change the width of the Email-Column and make it a little smaller.
This causes the ColumnHeader shift tu the left, so ColumnHeader and Columns are shifted mutually.
I think this is a bug in 4.1.1, in 4.1.0 it looks good.

Ext.create('Ext.data.Store', {
    storeId:'simpsonsStore',
    fields:['name', 'email', 'phone'],
    data:{'items':[
        { 'name': 'Lisa',  "email":"lisa@simpsons.com",  "phone":"555-111-1224" },
        { 'name': 'Bart',  "email":"bart@simpsons.com",  "phone":"555-222-1234" },
        { 'name': 'Homer', "email":"home@simpsons.com",  "phone":"555-222-1244"  },
        { 'name': 'Marge', "email":"marge@simpsons.com", "phone":"555-222-1254"  }
    ]},
    proxy: {
        type: 'memory',
        reader: {
            type: 'json',
            root: 'items'
        }
    }
});


var panel = Ext.create('Ext.grid.Panel', {
    title: 'Simpsons',
    store: Ext.data.StoreManager.lookup('simpsonsStore'),
    columns: [
        { header: 'Name',  dataIndex: 'name', width: 200},
        { header: 'Email', dataIndex: 'email', width: 100},
        { header: 'Phone', dataIndex: 'phone', width: 200}
    ],
    height: 200,
    width: 400
});
var win = Ext.create('Ext.window.Window', {
		title: 'Title',
		items: panel
}); 
win.show();

I couldn't reproduce this but it sounds serious. Could you provide a little more information?

Which browsers do you see this in? What OS?

Exactly which 4.1.1 build are you using (RC1, RC2 or the date of a nightly build)?

Could you include a screenshot of what you're seeing, just to confirm that we're looking for the same problem?

Attached three screenshots. The first open after the application. Then I scroll to the right.
Then I move the mouse slightly to the right so that the Email column is wider. When I let go of the mouse, the header pushes to the right and it looks like the last picture.

I use Ect 4.1.1 RC2, Windows 7, Firefox 13

This seems to be corrected in the latest build. I was able to duplicate this in 4.1.1 RC2

Open; scroll to right, resize email smaller, then resize larger .. not aligned.

If you have access to the nightly build, please try.

Scott.

Thanks, I've tried the nightly build and now the problem no longer occurs.
