most of the advice on the topic refers to adding the typeFilterLevel="Full" to my config, and I have done that, and the error still persists. Perhaps I am missing something obvious. Any help would be appreciated.

as noted above, I already have the typeFilterLevel="Full" set. So, this is not the problem. Also, I am using a binary package, so the soapsuds aspect of the article is irrelevant, and the config aspect is useless. Would you mind taking a second look and let me know what I am doing wrong?

I'm not sure ab out the cause of this, but here are some similar threads that might be helpful: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=4853 http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=5004
