Hi All,

I have just upgraded to rails 2.1 woop! All running smoothly but it  
seems that the instance variables aren’t being passed into my xml  
builder.

Is there any particular reason I have over looked?

Cheers  
Andrew

Anyone else experienced this?

Ryan,

How do you even get XmlBuilder to work in 2.1?

See: [Where did Builder::XmlMarkup go in Rails 2.1? - Rails - Ruby-Forum](http://www.ruby-forum.com/topic/156227)

I wonder if I will have the same issue once I can actually instantiate  
my builder.

What seemed to have happened is that if you pass a variable called  
@url in it get’s nillified - changed the variable name and it seemed  
to have worked.
