I'm getting a NullPointerException when I attempt to edit a record. I believe this is due to the fact that my keys are UUIDs. I am able to successfully edit entities that use a Long as a Key, but all my other entities use UUIDs and get this error.
Here is where the error occurs:
public Result show(String key) {
Object k = this.keyConverter.convert(key);
return this.delegate.read(k);
}
I believe this.keyConverter == null;
Here is the stack trace:
