We're very excited to be part of this global community. Look forward to talking to you in the Japanese Community !

Thanks, Benjamin.

I meant that the row I created through the API did not show up via SQL so that your explorer demo didn't work. 

I checked the domain definition, and the allowCustomUpdates flag was true. 

I will look and see if there is anything else that I am missing, and get back here..

Thanks, Benjamin.

Calling SetParameter() after saving the created domain worked perfectly.

I understand that working with Domain Definitions is more convenient in most cases, but I was looking for a way to deal with a situation where several domains need to be created by a user who is not so familiar with COS, and I thought it would be good to write code that creates a domain and feeds data.
