I have an editor screen with a tabsheet. One tab shows the Account details and the other tab the Comments. The main datasource of the editor is the Account. In the Comments tab I have a textfield to enter a comment and a button to post the comment. Underneath I have a table with the comments for that account. How do I save the comment? I understand that the commit() method from the AbstractEditor refers to the main datasource and so would not save the comment. So how am I able to use the AbstractEditor methods releated to the comments datasource?
