[TM4J-users] number in a Tolog query

[George T. <geo...@fr...>]

Hello,

I have a topic type with id=11998
the topic type has a SourceLocator=<topicMapName>#11998

the Tolog call
select $T from topic($T), instance-of($T,11998)?
gives me "Error parsing query string."

also the calls
select $T from topic($T), instance-of($T,'11998')?
select $T from topic($T), instance-of($T,"11998")?
are not acceptable

when I replace the 11998 id with some no number text the call works OK

Is there any solution on how to use numbers in Tolog representing IDs?

Cheers
George

The problem is, that the lexer interprets the number as INT and the
parser does not pass INTs to predicates. This failure is somehow
related to the failure Thomas Munch detected some days ago and the bug
with the value predicate (this failure is described in the bug
tracker. I believe you've submitted it).

I'll work on the issues and provide some patches next week.

Best regards,
Lars

Hi all,

Just for the record: I think this error is correct, because the 11998
MUST be interpreted as Integer.

As workaround you can try to use the object id notation @<ID>.

Nevertheless the parser/lexer has to be fixed.

Best regards,
Lars
