json script: read transition properties

[paalzza <paalzza gmail com>]

hello all

i'm facing a problem when not all transition properties can be read from 
script
there is no error, the property values seem to be just ignored, not 
affecting the transition

my json for transition is

    {
        "id": "transition_opacity_2",
        "type": "ClutterPropertyTransition",
        "property-name": "opacity",
        "duration": 1250,
        "from" : 255,
        "to": 0,
        "signals": [
            { "name": "stopped", "handler": "transition_stopped" }
        ],
        "auto-reverse": true,
        "loop": true,
        "repeat-count": 4,
        "delay": 500
    }

the
        "duration": 1250,
        "from" : 255,
        "to": 0,
        "signals": [
            { "name": "stopped", "handler": "transition_stopped" }
        ],
but
        "auto-reverse": true,
        "loop": true,
        "repeat-count": 4,
        "delay": 500

do not - whether they are there or not - this does not make any changes 
to transition behaviour.

why does this behave that way? i looked thru the code - as i understood 
simple properties are just being set with g_object properties functions. 
why these are not being set?
