If you're not using the proxy, then HTTPService is ultimately using 
flash.net.URLLoader to load and receive the data. You could try to take Flex 
out of the equation for a second and try the raw URLLoader API to see if it 
still occurs there.

Subject: Re: [flexcoders] Special characters after end tag of XML document 
(HTTPService issue)



Peter,

I have not made any changes to the XML.ignoreWhitespace property.

I have implemented the trim as suggested, and I have also put a check
to see if the last character of the string is a > (a quick way to see
if there's trailing junk characters).

What I'm experiencing now is the same issue as before, however now I
can see the trailing characters traced in my flashlog. Just as a
sample, `á!àê!àî!`á! ï! appears at the end of one of them.

I have noted that we are experiencing this with more than one servlet
at this point, it appears that all of the servlets in our application
might be affected.

Any other thoughts/suggestions?

Thanks again,

Brian
