ExtJS 4 combobox shows valueField instead of displayField on form bind
提问by Manuel
I got a extjs 4 combobox within a form bound to a model. I am binding data from grid to combo using form.loadRecord(record). The combobox is showing the valueField coming from the model assigned to the form instead of the displayField. The store of the combobox is preloaded. How can I achieve that the combobox shows the displayValue loading a record in the form?
我在绑定到模型的表单中得到了一个 extjs 4 组合框。我正在使用 form.loadRecord(record) 将数据从网格绑定到组合。组合框显示的 valueField 来自分配给表单的模型而不是 displayField。组合框的存储已预加载。如何实现组合框显示 displayValue 加载表单中的记录？
{xtype:'combobox',
fieldLabel: 'category',
name: 'categorySelId',
store: 'Categories',
queryMode: 'local',
displayField: 'label',
valueField: 'id',
anchor:'96%',
loadMask: true,
typeAhead: true,
forceselection: true,
valueNotFoundText: 'Nothing found'}
The store is already used in the grid to show the column category
store 已经在网格中使用，用于显示列类别
{ header: 'Category', dataIndex: 'categorySelectedId', flex:5,
renderer: function(value,metaData,record) {
if(value) {
var Categories = Ext.getStore('Categories');
var catRecord = Categories.findRecord('id', value);
return catRecord ? catRecord.get('label'): record.get('categorySelected');
} else return "";
}
},
Thx for your help!

The problem was that I have not had configured the correct types in the model. Setting the right type in the model solved the problem. Thx sha for helping!
问题是我没有在模型中配置正确的类型。在模型中设置正确的类型解决了这个问题。谢谢你的帮助！
