[OpenLayers-Dev] native JSON

some revisions ago the JSON.js is changed to use the native browser 
possibilities. But now arrays are in double quotes(see example below) 
and our backend has problems with deserialize it. As I know it is that 
the JSON format has no double quotes around arrays. So where is the 
error, is the native serializer(Firefox and Chrome) not producing a 
standard format? With the old code (before native browser function is 
used) all was fine.
The object we pass to the OL.Format.JSON.write has the 
features-attribute as array I tested it in firebug/chrome-dev-tools. I 
don't know why it should be a string after serializing.


"features":"[{\"type\": \"Feature\", \"id\": 
\"OpenLayers.Feature.Vector_339\", \"properties\": {\"gid\": 101225, 
\"title\": \"VREDEN\", \"ownerType\": 1, \"style\": {\"label\": \"<font 
color='#FF0000' bold='false' italic='false' sizeFactor='1' >[Â</font>\", 
\"fontFamily\": \"SprachGIS-Symbole2\"}, \"symbols\": [26373, 26367], 
\"wktGeometry\": \"POINT(759321.378649999 6806065.527048201)\"}, 
\"geometry\": {\"type\": \"Point\", \"coordinates\": [759321.378649999, 
6806065.527048201]}}, {\"type\": \"Feature\", \"id\": 
\"OpenLayers.Feature.Vector_341\", \"properties\": {\"gid\": 101252, 
\"title\": \"MILLINGEN\", \"ownerType\": 1, \"style\": {\"label\": 
\"<font color='#FF0000' bold='false' italic='false' sizeFactor='1' 
Has someone the same experience?
Thanks for help in advance.
