I have a tree panel set up in grid mode with one column, declared explicitly as a treecolumn:

Code:
 columns: [ {
                        xtype: 'treecolumn',
                        text: 'text',
                        dataIndex: 'text',
                        renderer: function (value, metaData, record, row, col, store, gridView) {
                            if (record.data.languageNode) {
                                return '<span class="bl-lang-node">' + value + '</span>';
                            } else {
                                return '<span class="' + record.data.tdCls + '">' + value + '</span>';
                            }
                            return value;
                        }
                    }]


The nodes of the tree I pass to setRoot includes several properties that are not declared as columns; they are there to provide data to the renderer.

Unfortunately, my properties are not there on the record.data. It's as it this is a copy made that only contains those attributes relevant to the declared columns or something.

What's going on?
