Can't add sort to selector without crazy error

[hellomoto]

I have

$select = 'template=post, when<=now, sort=when, ';
$results = $pages->find($select);

then output the results' data. It works fine without the sort=when. With it, I get this:

Error: Exception: SQLSTATE[42000]: Syntax error or access violation: 1066 Not unique table/alias: '_sort_when' (in /Applications/AMPPS/www/website/wire/core/PageFinder.php line 384)

what is this

I have this elsewhere

$start = date('Y', $pages->get($select.' sort=when')->getUnformatted('when'));

and it works fine, returns the earliest year.

Have you tried without the trailing comma?

[hellomoto]

That did it. I always have the trailing commas is why I didn't try it... oy thank you...
