Fields with tableName not editable

[jay.l.fisher]

I have a data source with customSQL for the fetch operation that joins various files. The update/add/remove operations are all implemented by custom code on the server side. Since some of the fields come from different tables I have specified tableName="otherTable" on the field tags in the ds.xml. Unfortunately, this seems to make them non-editable when I add them to a DynamicForm. My server side code will take care of the updates to the other table. How do I get them to be editable on the form?

Set them canEdit=true to override the default of being not editable.
