I’m doing a Web Services using SOAP, but when I click a button, the  
browser shows this message:

undefined method `parent’ for  
#\<SOAP::Parser::ParseFrame::NodeContainer:0x715fd7c @node=nil\>

And the error line is in =\> app/controllers/users\_controller.rb:10:in  
`alta’:

8| def alta  
9| client = ActionWebService::Client::Soap.new(SegurosApi,  
“[http://localhost:3000/seguros/api](http://localhost:3000/seguros/api)”)  
10| @service\_output = client.alta(params[:file]) # Error  
11| end

Anybody know why is the problem?

Thanks and greetings.
