RE: Wt::Dbo - Added by V. Bekir Macit about 10 years ago

the problems is about that:

I wrote in .h

template<class Action> void persist(Action&);

and in .cpp

template<class Action> void User::persist(Action &a)
{
dbo::field(a,name,"name");
dbo::field(a,password,"password");
dbo::field(a,role,"Role");
dbo::field(a,karma,"karma");
}

and it gaves that problem.

when I write all of them in .h

it doesnt have any problem!

what causes this?
