In general, I agree with Wolfgang. It is better to redefine the macro at 
an outer level. You can even do:

\defineframedtext[Solution]

\startnotmode[solution]
\definebuffer[Solution][local=yes]
\stopnotmode

However, in the few cases that you actually need to check for a mode 
inside a macro, you can use \doifmode ... etc.
