Hi,
Check if your method has the signature like this:
func (d DP) MyMethod(<my paramaters>) <my return types> { ... }
If so, change to this:
func (d *DP) MyMethod(<my paramaters>) <my return types> { ... }
I made this error so many times: a method called by value changes the value
of the object and the change vanishes when the method returns, you must use
a reference in order to preserve your changes to the struct fields.
Cheers,
Luis Otavio de Colla Furquim
