In the GData JS library, in IE, AuthSub fails if google.load("gdata",
"1.10"); is asynchronous, after the page has finished processing. For
example, if i place the google.load("gdata", "1.10"); call within the
GWT onModuleLoad method, then AuthSub stops halfway.
To avoid this we can directly add the following at the top of the GWT
html page:
<script type="text/javascript" src="http://www.google.com/jsapi";></
script>
<script type="text/javascript">google.load("gdata", "1.10");</
script>
Or just use the auto-load feature of the JS API to collapse these two
into a single script load.
But this wouldn't make use of the AjaxLoader module and it means that
the GWT app will have to wait for the GData libraries to load before
rendering, etc, instead of doing something like the following:
public void onModuleLoad() {
//render main app here
GData.loadGDataApi(null, new Runnable() {
public void run() {
initialize();
}
});
}
I don't know the reason for this behavior but it could happen if the
gdata library uses document.write for example.
