I have the follow notebook
and as you see in the follow image the field has information
IBGE COLUMN V6318
but when i used with the follow code observable assume that is all null.
WITH THE FOLLOW CODE
viewof IBGE_TOTAIS_X_EDADE_DEIXO_TREINAR = IBGE
I dont know what is the bug seems to be something related to the information saved in cache seems to be.
