Ext.ux.RowExpander - DoubleClick incurs error

[SYZ]

Hi All,

I'm using the Ext.us.RowExpander plugin with Sencha Architect. I've got the following error in my console (but the app still runs) whenever I double click on the item.

Ext.applyIf(me, {            items: [
                {

                    plugins: [{
                        ptype: 'rowexpander',
                        rowBodyTpl : [
                                '<p><b>Company: </b>{company}</p>',

                        ]
                    }]
                },

How do I solve this problem? Thanks a lot for your help.
