Description: ========== HTTPRequest has been deprecated since GWT 1.5 in exchange for RequestBuilder. I propose that we remove HTTPRequest from the API completely.
Why the sudden interest in axing code? ============================== HTTPRequest has a bug that causes IE8 to show a popup error message. HTTPRequest sets xmlHttp.onreadystatechange to HTTPRequestImpl::nullFunc, but HTTPRequestImpl::nullFunc is never initialized and is actually null (not a function). In the latest version of IE8, this results in an error popup and causes our tests to fail. It looks like older versions of IE ignore it. The problem is that HTTPRequest uses HTTPRequestImpl::nullFunc without creating an instance of HTTPRequestImpl, and thus never initializing nullFunc. It looks like HTTPRequest was refactored at some point not to use HTTPRequestImpl except for its nullFunc. Why not just fix it? =============== HTTPRequest has been deprecated since GWT 1.5, so its ripe for removal. In addition, it looks like we've already run into similar problems with XMLHttpRequest, where we've specifically noted that "[re]using the same function object kills HtmlUnit". Surprisingly enough, maintaining two versions of the same code leads to bad things. Thanks, John LaBanca [email protected] -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
