Hi,

You are missing to initialise the Voyage repository. I don’t know how is explained in the Mooc, but you will probably need to do something like:

VOMemoryRepository new enableSingleton.

Cheers, Esteban

Hi Esteban.

actually I'm using an External Mongo database and in the MOOC the initialization of Voyage Mongo repository, is done like:

TBBlog class >> initializeLocalhostMongoDB | repository | repository := VOMongoRepository database: 'tinyblog'. repository enableSingleton.

TBBlog class >> reset self initializeLocalhostMongoDB

and in my code I'm doing exactly like above. but interestingly when I wanted to reset the cache of Voyage by: VORepository current reset

again I've got another Error saying: "MessageNotUnderstood: receiver of "reset" is nill”.

Which again, should means you never executed initializeLocalhostMongoDB method. Can you try doing: TBBlock initializeLocalhostMongoDB. Esteban

thanks anyway!
