[4.2.0.265] Bug or Feature with RowEditing(?) and multiple, same dataIndex usage

[jheid]

Hi.

I have had the problem that no value is set in a rowediting grid combox editor.
When editing, the combobox didn't get any value although the value was there in the record.

The problem (bug or feature) was that I used two columns with the same dataindex - one for a small icon, the other for editing:

columns: [
 { text: '', dataIndex: 'type', renderer: function (v) { ... } },
 { text: 'Type', field: { xtype: 'combo', ... } }
 ] 

I thought this should do but with this approach there's a bug/feature in Ext.form.Basic.js in the method findField

findField: function(id) {
        return this.getFields().findBy(function(f) {
            return f.id === id || f.getName() === id;
        }); 

because there's not only the combobox, but also a Ext.form.field.DisplayView with the same name (for the renderer).

To fix this the findField has to be able to return multiple fields or it's not intended to use several columns with the same dataIndex which IMHO would be sad.

Cheers,
Jörn

It's entirely possible that you may have the same dataIndex in multiple columns so I have opened a bug in our bug tracker.
