我在GUI中有一个SimpleComboBox,它也包含一些重复的项目。假设有3个项目与“域”相同。当我选择第二个“域”或第三个“域”时,所选项目和所选索引始终指向“域”的首次出现。我如何更正,以便所选的索引/项目是正确的,而不是第一次出现项目?
具有重复值的ComboBox:
当我在第四次出现时选择“域”时,它总是指向“域”的第一次出现。
输出:
当我在最后一次出现时选择“192.168.1.30”时,它将指出第一次出现“192.168.1.30”。
请任何人帮助我。

请帮帮我。提前谢谢。

我没有使用Ext-gwt只是标准的ext-js,但我想我知道你需要什么!您应该定义显示和值字段。
Ext.create('Ext.form.ComboBox', {
store: xyz,
queryMode: 'local',
displayField: 'name',
valueField: 'id',
renderTo: Ext.getBody()
});
您必须确保重复的项目获得唯一ID。我认为如果在ext-js中这是可能的,那么在ext-gwt中也应该是可能的!
