"Solution exception:Object reference not set to an instance of an object" after reopeding a definition

Hi, I have a definition with the component "replace menbers" . A the beginning it works, but if I close and reopen the the definition, this component have this error: "Solution exception:Object reference not set to an instance of an object". Anyone knows how to solve the problem?

Thank you in advance,

Valentina

Quite probably you forgot to internalize your data and/or GH failed to memorize them (happens frequently)

Thank you, probably this is the problem, but how can I do?

For all the referenced data used in any GH def (referenced from the active Rhino file, that is): either internalize them or (better) use the Rhino file as well. Keep in mind that internalizing fails frequently when using Breps (but works OK with Points and Curves).

Of course diagnosis based on some error message is rather impossible:

If you have some error to report or you need help ... ALWAYS attach a SIMPLE related definition (isolating the problem) AND the Rhino file (in case that something is referenced - better safe than sorry).
