Comment (by [EMAIL PROTECTED]):
I had troubles reproducing it in a simpler setting. What I did notice
right now though, is I was calling mkElement oddly. Its type is
{{{mkElement :: (ArrowXml a) => QName -> a n XmlTree -> a n XmlTree -> a n
XmlTree}}}
but I'm calling it with a list ([sattr ("xmlns:" ++ pfx') ns]). Changing
the call to
{{{mkElement qn' (sattr ("xmlns:" ++ pfx') ns) cs}}}
and the error disappears.
Tried this in ghci:
{{{
:t mkElement undefined (sattr "" "")
mkElement (undefined) (sattr "" "") :: (ArrowXml a) => a n XmlTree -> a n
XmlTree
:t mkElement undefined [sattr "" ""]
<no output at all>
}}}
So something fishy is happening. If I pass in an empty list instead
{{{
:t mkElement undefined []
Couldn't match expected type `a n' against inferred type `[]'
Expected type: a n XmlTree
Inferred type: [a1]
In the second argument of `mkElement', namely `[]'
}}}
