Description Carlos Garcia Campos 2017-07-18 05:19:28 PDT
It currently returns early if page, frame or scriptObject are nullptr, in which cases the UI process is not notified. This causes test testShouldNotBeAbleToDoAnythingTheFrameIsDeletedFromUnderUs to hang, because message DidEvaluateJavaScriptFunction is never sent when the given frame no longer exists. We should send DidEvaluateJavaScriptFunction with WindowNotFound in case of page is nullptr and FrameNotFound if the frame is nullptr. The scriptObject early return is actually wrong, because scriptObjectForFrame creates a new script if there's isn't one for the given frame.
