I have to admit i had a bit of trouble understanding your scenario. Not
sure i do completely.
Regarding the Browser widget, it is simply a wrapper around an iframe,
so the standard security restrictions of modern browser apply. However,
it might not take into account any changes to document.domain. As far as
i understand it, it has to be set in both the parent frame (RAP) and the
iframe (document loaded in browser widget). You'd have to do that
manually for both.
I looked at the code, and in case the iframe is not yet fully loaded,
the widget uses the URL to determine if the document will be accessible
after it is loaded, without trying it first. If the iframe is already
loaded, this is done by trial and error, so you might want to try to use
a ProgressListener to wait until the document is loaded to create the
BrowserFunction. Perhaps that helps.
