[maplab-users] Query Object

[Adriano Hantequeste Gomes]

Hi All,

I modified the code and I arrived below at this stage, when I consult
a District (quarter) - "Bairro" that is seen in view of the map, does
not happen nothing, only one "refresh" in the navigator (to browser),
but when I consult a quarter it are of view of the map happens this
error:
