Context in nested repeat #221

I have a form (below) with a nested repeat in which I'd like to reference the current context node in an XPath expression. This doesn't work. However, if I define a variable to capture the context node within the nested repeat, then I can reference it from the XPath expression. Shouldn't I be able to use context() in this context? :)

Yes, came across this issue myself. We'll investigate - btw, another way that might work here is to use an idref with the the context function

context('inner-repeat')

given the inner repeat has that id. This should work but of course would be nicer with requiring that.
