json.xq regression in 1.4rc?

[Joe Wicentowski]

Hi all,

I have noticed one odd issue since updating my pre-production code to
recent builds of 1.4rc (I'm now updated to rev.10307).  The problem is
that my json.xq is now returning hundreds of errors in exist.log,
identical to this:

> 2009-10-31 19:29:29,643 [P1-9] ERROR (FunDistinctValues.java [compare]:176) - cannot compare valuesXPTY0004 : cannot apply operator to QName

Below is the code that generates the problem.  I have enabled the json
module in conf.xml.  You'll see below a single "items" element; I've
trimmed this down from 177 such "items" elements.  Even the 1 "items"
element in the example below generates 75 errors - so I get 75 x 177
errors!:

===
import module namespace json="http://www.json.org";

let $xml :=
<root>
    <items>
        <type>Milestone</type>
        <label>1750-1775: Diplomatic Struggles in the Colonial Period</label>
        <xmlid>1750-1775</xmlid>
        <period>1750-1775</period>
        <id>1</id>
        <imageURL>/images/milestones/1750-1775.jpg</imageURL>
        <imageWidth>200</imageWidth>
        <imageHeight>200</imageHeight>
        <imageAlt></imageAlt>
        <url>/milestones/1750-1775</url>
        <inDate>1750-01-01</inDate>
        <outDate>1775-12-31</outDate>
    </items>
</root>

return json:xml-to-json($xml)
===

Does anyone have any idea what could be causing this?  I mention less
because of any immediate urgency, but rather because I wonder if it's
related to any other changes to predicates, etc. that have entered the
code recently?  I'd be happy to do more tests or provide more info if
it would help.

I removed the log message. The exception reported in the message is
expected and should not be considered an error.

I've rebuilt and can confirm that the error messages are no longer present.

Thank you!
