Error in displaying custom Google Map in Polymer -
i displayed simple google map : <google-map latitude="30.283" longitude="57.083" zoom="12" language="fa" disable-default-ui > but when try add position style, doesn't apply , zoom control disappears, guess problem in way add additional-map-options , don't know how fix it: <google-map latitude="30.283" longitude="57.083" zoom="12" language="fa" disable-default-ui additional-map-options='{"zoomcontrol" : "true", "zoomcontroloptions" : {"style" : "google.maps.zoomcontrolstyle.small", "position" : "google.maps.controlposition.bottom_right"} }'> huh... turns out polymer not know google.maps.controlposition.bottom_right ... knows int 9 ... <google-map latitude="30.283" longitude="57.083" zoom="12" langua...
