I cannot post any entry into the miscellaneous journal because no default accounts are setup for this journal. ok I setup default accounts!

This journal is precisely a journal where one should be able to post any kind of accounting entries, without default accounts.

Shall we be obliged to setup "dummy accounts" as default and then obliged to change these everytime we need to post entries?

Other journals are concerned: bank journals, opening entries journal.

The concept of default accounts in journals should be limited to sales and purchases.
