Cannot pass object as perm to map.

[rahman973]

while creating a product we make a map. which works fine for simple attributes, but is not working for object type attributes.

dimensions.setLength("1");
        dimensions.setWidth("1");
        dimensions.setHeight("1");
        Gson gson = new Gson();
        String json = gson.toJson(dimensions);

        productInfo.put("dimensions",json);

on printing, it shows JSON has the object of dimensions
{"length":"1","width":"1","height":"1"}
