解决Ext4.2.3中propertyGrid修改后点击排序报错

Ext4.2.3中PropertyGrid修改后点击排序报错,具体错误信息如下：

 

一开始还怀疑是自己哪里配置错了,各种尝试结果还是一样。查遍百度和谷歌，无果，只有一篇帖子说是4.2.4修正了。还是自己动手吧，自己动手丰衣足食。

点开报错地方(如下图所示)，原来是me.field.column没有定义。

 

然后继续找，找啊找啊找到Ext.grid.property.Grid的getCellEditor方法。此方法有参数column,可在方法体内，column就没有被用到过，于是就感觉问题出在这里。

经过实践，讲此方法修改如下，此bug就解决了。

 

    getCellEditor : function(record, column) {
        var me = this,
            propName = record.get(me.nameField),
            val = record.get(me.valueField),
            editor = me.getConfig(propName, 'editor'),
            type = me.getConfig(propName, 'type'),
            editors = me.editors;
        
        if (editor) {
            if (!(editor instanceof Ext.grid.CellEditor)) {
                if (!(editor instanceof Ext.form.field.Base)) {
                    editor = Ext.ComponentManager.create(editor, 'textfield');
                }
                editor = me.setConfig(propName, 'editor', new Ext.grid.CellEditor({ field: Ext.apply(editor,{column:column}) }));
            }
        } else if (type) {
            switch (type) {


                case 'date':
                    editor = new Ext.grid.CellEditor({ field: new Ext.form.field.Date({column: column,selectOnFocus: true})});
                    break;
                case 'number':
                    editor = new Ext.grid.CellEditor({field: new Ext.form.field.Number({column: column,selectOnFocus: true})});
                    break;
                case 'boolean':
                    editor = new Ext.grid.CellEditor({field: new Ext.form.field.ComboBox({column: column,
                        editable: false,
                        store: [[ true, me.headerCt.trueText ], [false, me.headerCt.falseText ]]
                    })});
                    break;
                default:
                    editor = new Ext.grid.CellEditor({field: new Ext.form.field.Text({column: column,selectOnFocus: true})});
            }
        } else if (Ext.isDate(val)) {
            editor = new Ext.grid.CellEditor({ field: new Ext.form.field.Date({column: column,selectOnFocus: true})});
        } else if (Ext.isNumber(val)) {
            editor = new Ext.grid.CellEditor({field: new Ext.form.field.Number({column: column,selectOnFocus: true})});
        } else if (Ext.isBoolean(val)) {
            editor = new Ext.grid.CellEditor({field: new Ext.form.field.ComboBox({column: column,
                editable: false,

            })});
        } else {
            editor = new Ext.grid.CellEditor({field: new Ext.form.field.Text({column: column,selectOnFocus: true})});
        }
        
        editor.editorId = propName;
        return editor;
    }
