I'm trying to capture an error generated by Reader/Acrobat when the document attempts to execute a web service connected from an untrusted document/location.
So far, I've managed to use try catches to capture all the connection errors, except this one. The error message is displayed after the form is rendered and user clicks on a button executing the connection. The warning says 'Couldn't post data to URL' in addition to displaying the Yellow Bar. The goal is to have the form display a meaningful warnign instead of this one.
