internal problem and internal error
Added by Sebastian Fey about 8 years ago
I'm developing a xquery program with oxygen 18 which uses Saxon-EE 9.6.0.7. Everything runs fine in oxygen. But when I run the code with the latest .NET version (EE 9.7.0.8) I get an "internal problem" with one query and an "internal error" with another.

Hi,
Thanks for letting us know about the problem you have discovered. Is it possible that you can send us a repo so that we can investigate further. Either on this bug issue or privately if confidential.

"java.lang.NullPointerException: Internal error: expression $devices_ has no retained static context" I tested the query with the latest java version were it runs without an error. If you want I can look into that again and see if I can narrow it down when I got the time (not this week) or send you the whole code per email.

"Internal problem: Base value for indexed filter is not indexable "
the problem here seems to be a predicate of the form @/*[name()=$x]@ where $x is empty. I fixed the problem with a where clause, see comment in snippet.
for $action-type in $component/action-type
let $component-type := $project//components[id = $component/@id]/type
where exists($component-type) (: !!! this line fixes the problem !!! :)
return
{$matrix/*[name() = $component-type]/*[name() = $action-type]/@mode/data()}

Hi,
To reproduce the error we would need the full query file please.
RE: internal problem and internal error - Added by Sebastian Fey about 8 years ago
I can't send the full query, so I'll have to narrow it down, but here is another one (already narrowed down)
this query
declare variable $doc-devices := doc("out/devs-no-params.xml");
declare variable $doc-device-types := doc("res/device-types.xml");
declare variable $devices_ := $doc-devices;
copy $devices := $devices_
modify (
for $channel in $devices//channel
return
replace node $channel
with
{$channel/@*}
)
return
$devices
with this doc
gives me a NullPointerException:

RE: internal problem and internal error - Added by Michael Kay about 8 years ago
The problem occurs for me when running from the command line, but not when running 9.6 in my IDE. This suggests it's a bug that has been fixed since the last 9.6 maintenance release.
A search leads me to bug 2789 (see comment #4)
