Titanium开发遇到的一个‘isn't already in the context’ 错误

错误:
Adding an event listener to a proxy that isn't already in the context。

用 navGroup打开一个window,然后新建leftnavbutton,并注册事件,会报错:
Adding an event listener to a proxy that isn't already in the context。

一步步删代码,发现是事件注册问题。。

“A quick and dirty fix for this issue is to set the backgroundGradient AFTER you have created the button and added it to a view. This will put the button into the context and prevent this message from displaying.”

我觉得这句话有点道理,所以我加了settimeout来延时注册 button的事件,有一定效果额~

不知道这么做会有什么后遗症。。。 8)


setTimeout(function() {
leftButton.addEventListener("click", function() {
currentWindow.fireEvent("closeWindow");
});
}, 50);
