英文:
ComboBox onChange event does not fire
问题
I cannot seem to get the onChange event to fire in the xp:comboBox. The djComboBox works fine, but I have other issues with that which are not relevant here.
在xp:comboBox中，我似乎无法触发onChange事件。djComboBox可以正常工作，但这里不涉及与其相关的其他问题。
There is no issue with events such as onBlur
对于像onBlur这样的事件没有问题
These two snippets show the problem, I am probably missing something obvious, but any help is appreciated.
这两个代码片段显示了问题，我可能遗漏了一些显而易见的东西，但我会感激任何帮助。

你应该检查数据源而不是组件（使用 getComponent）。所以例如尝试：viewScope.xpcombo == "Cease"
英文:
You should check the data source instead of the component (using getComponent). So try for example: viewScope.xpcombo == "Cease"
