i using raphael draw paths. each path has associated rectangle [container] size , position of bounding box. using container dragging both shapes. in move callback, update both positions both move together. this works great until serialize. serializing path, creating container on fly after deserialization. immediately after converting json , back, things fine. can print out current transform of path , looks correct. doing transform on path after results in path being reset , moved 0,0. here fiddle shows problem. if move rect, can see both objects move together. if click 'save/load', things fine, , path prints same. if drag, path gets reset 0,0. printing shows transform has been reset 0,0. i trying find out how make path move did before serialization. getting lost in process? or there internal state needs updated? raphael.json serialises data stored in elements. not preserve temporary data stored in paper object indeed lost in process when ...
