Hi
I have valueGroupDataSource with this query
select pl.isdefault , art.code
from rental$Articles art
join rental$Pricelist pl on pl.articles.id= art.id
I load data to dataGrid and have exception like below. I see then first column tries to be mapping to string. Where is the problem ?
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
