Framework not identifying the undeclared UiHandler.

[shivakumarkn]

One of my views have an handler as follows -
@UiHandler("myHomePageAnchor")
void onMyHomePageAnchorClick(ClickEvent event) {
listener.onMyHomePageAnchorClicked();
}

Unless "myHomePageAnchor" is declared as an Anchor in my view (current code doesn't have it declared but works fine), the gwt-test-utils fails.

The stack trace in version .41 doesn't give much info and we don't even know the error is due to undeclared UiHandler. But the jar "gwt-test-utils-0.41-20120905.060017-3.jar" I downloaded from sonatype is good with some useful info shed on. i.e., it pinpoints to the view class. See the two different versions throwing different errors.

Stacktrace with 0.41-20120905.060017-3. The last two lines takes me directly to my error class.

This is something I mentioned as an issue 150 @ https://code.google.com/p/gwt-test-utils/issues/detail?id=150. Though I am not looking for the immediate fix, it would be great if the framework throws the error it used to throw earlier. That helps to identify the cause and just declare the troublesome field as a workaround.

Thanks

encountered the same problem, should be easy to fix?

Not worked on this framework for last few months. So not sure whether it is fixed. But the workaround is to declare the component in the view whether you use it or not.
