Hi!

I have a strange problem with ActiveResources:

When ActiveResource parses the following XML, it throws a RuntimeError  
and displays the following Error-message:  
“can’t typecast “[http://example.net/faktura](http://example.net/faktura) units.xsd””

the xml:

\<?xml version="1.0" encoding="UTF-8"?\>

1  
kg  
  
  
2  
ltr

When I remove the “xsi:schemaLocation”-attribute it works like it  
should.

I found the Rails-changeset where this message (“can’t typecast…”)  
was introduced, but that did not help me. ([http://dev.rubyonrails.org/](http://dev.rubyonrails.org/)  
changeset/7074?format=html&new=7074)

Does anyone know if the “xsi:schemaLocation”-attribute means something  
special to ActiveResource?

Thanks for any help and greetings,

- dominik

PS: I need this attribute for (pre-Rails) validation and so this is  
not a good solution! 😉

Rails can’t deserialize xml with namespaces. See:
