I was not able to duplicate this problem, can you duplicate your problem in a test case?
Code:
Ext.onReady(function(){
var store = Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'change'],
data:{'items':[
{ 'name': 'Lisa', "email":"lisa@simpsons.com", "change":100 },
{ 'name': 'Bart', "email":"bart@simpsons.com", "change":-20 },
{ 'name': 'Homer', "email":"home@simpsons.com", "change":23 },
{ 'name': 'Marge', "email":"marge@simpsons.com", "change":-11 }
]},
proxy: {
type: 'memory',
reader: {
type: 'json',
root: 'items'
}
}
});
var editor = {
xtype: 'textfield',
allowBlank: false
};
var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false
});
Ext.create('Ext.grid.Panel', {
title: 'Simpsons',
store: store,
columns: [
{ header: 'Name', dataIndex: 'name', editor: editor },
{ header: 'Email', dataIndex: 'email', flex: 1, editor: editor },
{ header: 'Change', dataIndex: 'change', editor: editor }
],
height: 200,
width: 400,
renderTo: Ext.getBody(),
plugins: [rowEditing]
});
});
