[Trilinos-Users] strange error setting parameter list

[Hoang Giang Bui]

Hi

I got problem with Teuchos::ParameterList again

At some place in my code I created a ParameterList

Teuchos::ParameterList p;

p.set("name", "BP");

Try to read it back at another place

std::string tmp = p.get<std::string>("name");

An error happens
RuntimeError: Error!  An attempt was made to access parameter "name" of 
type "string"
in the parameter (sub)list "ANONYMOUS"
using the incorrect type "string"!

Any idea how to get around this error?

BR
