[Exist-open] there should be an error in the xquery parser

Dear all,
this strange behavior is representing:
I have the following code fragment:
let $x :=
element UU {
element stereo1 {$role[1]/@AssociateItem}
,element stereo2 {$role[2]/@AssociateItem}
,$ont//*[@ID eq "X43ECC96601FB"]
(:,$ont//*[@ID eq ($role[2]/@AssociateItem)]:)
}
let $tmp := logger:log ("yyyy",$x)
Please, note the last element is commented. The result fragment, contained in the "yyyy" log file is the following:
<log>
<UU>
<stereo1 AssociateItem="X43ECC96601FB"/>
<stereo2 AssociateItem="X49745F050382"/>
<dvn:UseCase xmlns:dvn="http://egov.diviana.it/b121/DVN" ID="X43ECC96601FB" Name="Anagrafica Richiedente" Stereotype="use-case realization" ParentCategory="X43ECC9210011">
<dvn:UseCaseDiagram ID="X43ECCA3B00D5" Name="Anagrafica Richiedente" ZoomFactor="100" ParentCategory="X43ECC9210011">
.....
But now, if I change the code as follow
let $x :=
element UU {
element stereo1 {$role[1]/@AssociateItem}
,element stereo2 {$role[2]/@AssociateItem}
(:,$ont//*[@ID eq "X43ECC96601FB"]:)
,$ont//*[@ID eq ($role[2]/@AssociateItem)]
}
I got an exception. Note: I just commented the statement with the constant value and uncommented the next one, wich contains exactly the same value.
Please, note that the following query (with nested predicates) runs fine: $ont//*[$role[2][@AssociateItem eq $ID]]
I'm still running the 1.4.0 rev 10440 build 20091111 which comes with betterform limegreen.
I disabled all the automatic update.
Anyone can help?
TIA
Paolo

Oggetto: usual behavior is changed
Hi all,
from a couple of days I'm facing with a changed behavior in eXist.
I'm running the 1.4.0 rev 10440 build 20091111 which comes with betterform limegreen.
First of all, I didn't change any config in exist.
Suddenly, some queries running fine for more than a year, start to give back the same strange error (see below).
To correct the error, I must change some .xq statements, like the followings:
before: let $el := $ont//rdf:Description[mm:hasLegacyId eq $id]
after: let $el := $ont//rdf:Description[mm:hasLegacyId/text() eq $id]
before: let $asSubject := $ont/*/rdf:Description[mm:hasSubject/@rdf:resource eq $uuid]
after: let $asSubject := $ont/*/rdf:Description[mm:hasSubject[@rdf:resource eq $uuid]]
Please, can anyone explain this fact?
Thank you.
Paolo
