Really odd module behaviour

Question

This is very strange.
First, this works ok:
dbxml> setNamespace x http://www.example.com
Binding x -> http://www.example.com
dbxml> query 'declare function x:foo() as element() {<foo><bar></bar></foo>}; x:foo()'
1 objects returned for eager expression 'declare function x:foo() as element() {<foo><bar></bar></foo>}; x:foo()'
dbxml> print
<foo><bar/></foo>
Now lets do the same thing in a module:
doug@andari:tmp$ cat > x.xquery
module namespace x = "http://www.example.com";
declare function x:foo() as element() { <foo><bar></bar></foo>};
doug@andari:tmp$ dbxml
dbxml> setBaseUri "file:///home/doug/tmp/"
Base URI = file:///home/doug/tmp/
dbxml> query 'import module namespace x = "http://www.example.com" at "x.xquery"; x:foo()'
1 objects returned for eager expression 'import module namespace x = "http://www.example.com" at "x.xquery"; x:foo()'
dbxml> print
<foo/>
That's definitely wrong. I'm getting the same behaviour with all sorts of modules that worked perfectly well on 2.3.10. Since the forums aren't full of complaints, I'm guessing this is only affecting me. I've built the software on two machines though, and I get the same behaviour.
Any ideas how to track down what's causing this?
Cheers,
Doug.

Hi John,
I applied the patch and it fixed the issue. Thanks.
But I have encountered another issue related to import module. I have written up a simple test case to illustrate the problem.
I created two files, test01.xqm and test02.xqm, and put them in the same directory.
======= test01.xqm =========
module namespace test01="http://www.mydomain.com/xquery/modules/test01";
import module namespace test02="http://www.mydomain.com/xquery/modules/test02" at "test02.xqm";
declare function test01:main() as xs:string?
$test02:myString
declare function test01:main2() as xs:string?
test02:main()
========= test02.xqm ========
module namespace test02="http://www.mydomain.com/xquery/modules/test02";
declare variable $test02:myString as xs:string := "test02 has a string";
declare function test02:main() as xs:string?
$test02:myString
==========================
dbxml> setBaseUri "file:///home/lap/bdbxml/debug/"
Base URI = file:///home/lap/bdbxml/debug/
dbxml> query ' import module namespace test01="http://www.mydomain.com/xquery/modules/test01" at "test01.xqm"; test01:main() '
stdin:2: query failed, Error: A variable called {http://www.mydomain.com/xquery/modules/test02}myString does not exist [err:XPST0008], file:///home/lap/bdbxml/debug/test01.xqm:7:3
dbxml> query ' import module namespace test01="http://www.mydomain.com/xquery/modules/test01" at "test01.xqm"; test01:main2() '
stdin:3: query failed, Error: A variable called {http://www.mydomain.com/xquery/modules/test02}myString does not exist [err:XPST0008], file:///home/lap/bdbxml/debug/test02.xqm:7:3
dbxml> query ' import module namespace test02="http://www.mydomain.com/xquery/modules/test02" at "test02.xqm"; test02:main() '
1 objects returned for eager expression ' import module namespace test02="http://www.mydomain.com/xquery/modules/test02" at "test02.xqm"; test02:main() '
dbxml> print
test02 has a string
=================================
Looks like from test01.xqm, it can see test02:main() but not $test02:myString.
Any advice would help. Thanks!
