Query optimizer bug with nested for? - java.lang.NullPointerException at Path.index(Path.java:673)
Hi everybody!
Maybe it's a newbie issue, but I would like your comments.
I'm writing a RESTXQ method to search among a couple of databases. ( >100 databases )
Some databases are split into a couple of parts due to the number of nodes. For example US: it's separated into US00, US01 and US02.
So, my problem is:
if I replace "*for $usPart in ('US00')*" by "*for $usPart in ('US00','US01',''US02)*" in *QUERY [A]*, I get this error:
*Improper use? Potential bug?

Using "*for $usPart in ('US00')*" it works without any problem. With one element there is no problem, with two or more it fails.
Any ideas about what I'm doing wrong?
Here is the *QUERY [A]* ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- declare namespace gb="http://www.ipo.gov.uk/schemas/tm";
let $text:="christian" let $registries:=('GB','US')

Maybe it's a newbie issue, but I would like your comments.
…definitely something you shouldn't encounter as a newbie either ;) Thanks for reporting it.
Does the exception also occur with the latest snapshot [1]?

Hi Christian!, thanks for your reply :-)
I've just downloaded the latest snapshot [1] and executed the query [2], and yes: the problem is still there.

Hi Christian! Wow, you are like a Terminator of coding! XD
Is *BaseX933-20200511.231351.exe *( snapshot of 23:14 ) the latest version?

Hm, maybe it was the previous 9.3.3 snapshot you launched?
Feel free to provide me with a minimized query that allows me to reproduce the bug if it persists. On GitHub, I have referenced a query that I used for testing [1].
Best, Christian

Hi Christian!, thanks for your reply :-)
I've just downloaded the latest snapshot [1] and executed the query [2], and yes: the problem is still there.
Cheers, Sebastian.

…definitely something you shouldn't encounter as a newbie either ;) Thanks for reporting it.
Does the exception also occur with the latest snapshot [1]?

I'm writing a RESTXQ method to search among a couple of databases. ( >100 databases )
Some databases are split into a couple of parts due to the number of nodes. For example US: it's separated into US00, US01 and US02.
So, my problem is:
if I replace "for $usPart in ('US00')" by "for $usPart in ('US00','US01',''US02)" in QUERY [A], I get this error:

Using "for $usPart in ('US00')" it works without any problem. With one element there is no problem, with two or more it fails.
Any ideas about what I'm doing wrong?
Here is the QUERY [A]
declare namespace gb="http://www.ipo.gov.uk/schemas/tm";
let $text:="christian" let $registries:=('GB','US')
let $results := for $registry in $registries return switch ($registry)

Yes!, you were right!
I've bought a new 2TB M.2 disk to play with BaseX and I've got confused: instead of install in *A:* I installed the new snapshot on the old *C:*
Now it works like a charm !! [1]
Thank you very very much, Christian, by your time.
Best regards! Sebastian.

Hm, maybe it was the previous 9.3.3 snapshot you launched?
Feel free to provide me with a minimized query that allows me to reproduce the bug if it persists. On GitHub, I have referenced a query that I used for testing [1].
Best, Christian
