Subject: elementary/transit - fixed incorrect logic for recorvering objects' states-context.
X-Git-Tag: v1.0.0~2693
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=daa6030d7208124ba44472d2bd91e33790f2c41b;p=platform%2Fupstream%2Felementary.git

elementary/transit - fixed incorrect logic for recorvering objects' states-context.

when same objects are added to multiple transits which have chained relationship,
the objects couldn't be recovered their states incorrectly.
