I traced the bug in in the 1.1 release branch. The version of this file in trunk did not have this bug. Here is an example:


Instead of returning the value of the field, it returns the string "value".

I'm running "Foswiki version Foswiki-1.1.4, Tue, 20 Dec 2011, build 13483, Plugin API version 2.1" I have a similar issue:
Returns the string "comment" instead of the actual comment. When there is more than one attachment in the source topic however, the above works correctly.

This is fixed in Foswiki 1.1.5, which isn't released yet. You can try replacing your copy of with the current version in SVN, assuming this file is compatible with Foswiki 1.1.4 (I'm sure it is, but I haven't tested).

The changes were minimal (a single line)
www-data@foswiki:/var/www/foswiki/lib/Foswiki/Query$ diff /home/foswiki/
<         return $b->evaluate( data => $lval, tom => $domain{tom} );
>         return $b->evaluate( data => $lval, tom => $domain{tom} ) ? $lval : [];
I replaced the file and have to report that the above example still does not work; it returns a null string instead of the actual comment.

I tried & from trunk and can report that the above example does work as expected.

Flipping CurrentState back to New because this Item is not fixed in Foswiki 1.1.5

-- NigelWinterbottom - 26 Mar 2012

Confirmed - this is still broken on 1.1.5RC2.

Note that the attachments issue is a different problem, covered by Item11730.

-- GeorgeClark - 05 Apr 2012

changed state back to Waiting for Release - this patch fixes the problem in the case of a where clause that needs to be evaluated. Item11730 is the case of a where clause that is an array index.
