I've created a pageextension which extends /Bank Account Ledger Entries/ and sets Editable to true. I also set Editable to true on the Description field, which is the field I want users to be able to edit. However, this does absolutely nothing - the Edit List button is greyed out and the field does not respond when clicked. Is it not possible to make fields editable like this? The table itself does not seem to have Editable set to false, only the page in the base app.
