Improper use? Potential bug?
Hi Christian,
I encountered this error-message.
I have a strong feeling that this error is related to previous reports, see
. my email dd 13-05-2013 and 03-12-2014
My program is heavily recursive so it is hard to create a running snippet but I will try.
Hopefully in the mean time you can have a look at the error.
TIA,
Rob Stapper

We definitely need some code to track this down. Thanks in advance.
Hi Christian,
While stripping down my program I tumbled over an issue with the use hof:id-function. See attachment: "test hofID.xq". Shouldn't this work?
I don't know if of how it is related to the error-message but it could has something to do with it.

I don’t think so. What result would you expect?
Your query does quite a lot, and I can only guess what you think of it. Please reduce it further and tell us a) what you think goes wrong and b) which result you would expect.

a) I've reduced it to its essence. b) I would expect both versions behave the same. Thus: ( 1,2) as result

Hi Rob,
Your queries are not equivalent. The hof:id function simply returns its argument (see [1]). In your example, it returns a function with two arguments ($v1,$2v), which is then passed on to local:exists and bound to $exec. Later on, $exec is evaluated with a single argument, so this cannot work out (see the error message "1 argument supplied, 2 expected: $exec").

Hi Christian,
Thank you for the explanation. I interpreted what would happen obviously in a wrong way. But since I have a working solution I'll use that one.
Rob.

Hi Rob,
Our functional mastermind Leo has fixed a bug that may also fix your runtime exception [1]. Your feedback on the latest snapshot is welcome [2]. If the problem persists, you could set INLINELIMIT to 0 and report back to us what happens.
Cheers, and a big thank you to Leo, Christian
