i have used $email = $graph->getproperty('email'); still can not access email address , returning blank email. should do? thoughts?

have @ answer here:

you need specify each field want returned graph api starting v2.4, e.g.

$request = new facebookrequest($sess,'get','/me?fields=id,name,email');

it's in facebook docs.

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
