I try to create a very simple "language" for simple double-entry bookkeeping. So far ConceptDeclarations for Root (containing Accounts and Transactions), Account, Accounts (containing Account's), Transaction, Transactions (containing Transaction's) got created.
Now I'm stuck at the Accounts_Editor, which simply should contain a horizontal layout with a constant text ("Accounts:") and a vertical list of the available accounts. How do I show a list of accounts (0..n aggregation of ConceptDeclaration Account's)?
Also, a Transaction references a 'credit' and 'debit' Account. How do I make the Account's choosable in the Transaction_Editor?
Thanks in advance.
