Summary: PF: pf:mil() can't deal with nil values in MIL results
Initial Comment:
If the result of the MIL code passed to pf:mil() is a BAT, and it contains nil
values in its head, or tail, error will happen when translating the MIL result
into XML elements, in elem_constr():
xquery>pf:mil('var a := new(str,str); a.insert(str_nil, "abc"); return a;')
more><>
MAPI = [EMAIL PROTECTED]:50000
QUERY = pf:mil('var a := new(str,str); a.insert(str_nil, "abc"); return a;')
ERROR = !ERROR: mposjoin: all BATs in the tail of the third input BAT (ws_item)
must have a dense head.
!ERROR: CMDmposjoin: operation failed.
!ERROR: interpret_params: fetch(param 1): evaluation error.
xquery>pf:mil('var a := new(str,str); a.insert("abc", str_nil); return a;')
more><>
MAPI = [EMAIL PROTECTED]:50000
QUERY = pf:mil('var a := new(str,str); a.insert("abc", str_nil); return a;')
ERROR = !ERROR: mposjoin: missing matches. The result requires the same number
of tuples as the first two input arguments: 1 < 2.
!ERROR: CMDmposjoin: operation failed.
!ERROR: interpret_params: fetch(param 1): evaluation error.

Jan,
Thanks for looking at this. I assigned it to you because cvs said the code
was latestly checked in by
you, but it doesn't have to mean you are responsible for fixing it. I will
try to fix it myself.
Regards,
Jennie

I'm definitely not responsible for pf:mil and elem_constr() is a
deprecated proc. If you in addition use elem_constr() incorrectly it of
course fails.
What you would need is to turn nil values in ws_mil() into real strings
instead of str(nil).
If you want to use pf:mil please fix it yourself.
