Description Tim Mills 2007-01-19 13:49:31 UTC 
The multiplication operator here fails to typecheck becuase local:multiplySequence is typed as item()*.

(: Date: 2007-01-15T15:15:45+01:00                       :)
(: Purpose: A recursive function multiplying a sequence. :)
(:*******************************************************:)
declare function local:multiplySequence($input)
{
    if      (empty($input))
    then    1
    else    $input[1] * local:multiplySequence($input[position() != 1])
};
local:multiplySequence((1, 2, 3, 4, 5))
Comment 1 Frans Englich 2007-01-21 12:45:55 UTC 
A fix has been attempted in CVS, and XQTS_current.zip has been updated to contain the new change. If it can be verified that the change is correct, it would be appreciated.

If this resolution is satisfiable, feel free to change status to closed. Otherwise, reopen this report. If no opinion on the resolution is expressed within two weeks, I will change status to closed.

This change to this report was part of a batch-change of several reports.
Comment 2 Tim Mills 2007-01-22 08:49:36 UTC 
This still fails.  I suggest:

declare function local:multiplySequence($input as xs:integer*) as xs:integer

which ensures that the multiplication operator will type check correctly.
Comment 3 Frans Englich 2007-01-23 16:20:20 UTC 
A new attempt has been committed to CVS(see comment #1).
Comment 4 Tim Mills 2007-01-23 17:33:30 UTC 
K2-FunctionProlog-9 is now fixed.  Thanks.
