ExtJS EditorGridPanel display Error

I have a problem with a Ext.Grid.EditorGridPanel, I am currently using ExtJS 2.3.0, that can't be changed. :-(

Following the problem:

I created a window which consist of 2 FormPanel and between them the EditorGridPanel. For the viewConfig of the grid, there is only "forceFit=true" set and no style or view options set for the ColumnModel. Only for each column the align option is set to "center". The ColumnModel consits of 13 columns, more or less text only. Now I open the website I am working on with a browser and open the window to test the GUI. When I try to switch between the cells in a single row the entire data row moves to the left, so that the first cells are no more shown. After adding a new row to the grid (via an add button) the view resets and all cells for each column are displayed correctly again. The column headers and the tbar are fixed and always correctly rendered.

The problem occurs with IExplorer 8.0x, an older Firefox version (2.0x), but the grid works fine with Firefox 3.6x and Safari 5.0x. If someone had a similar problem and got it fixed or an idea what may causes that problem, feel free to answer. ;-) Many thanks in advance!

First of all, it looks like you have some JavaScript syntax errors. I know you only posted a snippet of your code, but try running the whole thing through JS Lint.

For starters:

this.gridRecord:  Ext.data.Record.create([
    {name:'id', type:'int'},
    {name:'start', type:'string'},
    {name:'end', type:'string'},
    {name:'mo', type:'boolean'},
    {name:'tu', type:'boolean'},
    {name:'we', type:'boolean'},
    {name:'th', type:'boolean'},
    {name:'fr', type:'boolean'},
    {name:'sa', type:'boolean'},
    {name:'su', type:'boolean'},
    {name:'type', type:'string'}
]);

Should be:

this.gridRecord = Ext.data.Record.create([

While I'm not entirely sure this would cause the problem, I see that your column configs have widths assigned to them. Even though you are setting the viewConfig property "forceFit: true", I suspect that the editor may attempt to use the widths you have set for each column.

See if that clears up anything.

Thanks, but the code snippet has a copy and paste error, the gridRecord is a global property at the original code. I overlooked that as i modified the code, sorry for the confusion.

Now I tried your suggestion and found the culprit: It seems like IE can't handle the "forceFit" option at all, I commented out that option and set the width for each column and... it worked fine, no column moves! No I inserted a work around, first I check if the browser is an IE if not the "forceFit" option is set to "true" else "false".

Many thanks for your help!
