Android realm.io: Row/Object is no longer valid

问题

This is my delete function and it does find the workday1 object:

public static void delete(Context context, Workday workday) {
    Realm realm = getRealm(context);
    realm.beginTransaction();

    Workday workday1 = realm.where(Workday.class)
            .equalTo("date", workday.getDate())
            .equalTo("hours", workday.getHours())
            .equalTo("minutes", workday.getMinutes())
            .findFirst();

    workday1.removeFromRealm();
    realm.commitTransaction();
}

When it executes the removeFromRealm method it crashes:

java.lang.IllegalStateException: Illegal State: Row/Object is no longer valid to operate on. Was it deleted?

How can I fix this? Any help would be greatly appreciated.

UPDATE (I can print the content returned by the following method):

    Workday workday1 = realm.where(Workday.class)
            .equalTo("date", workday.getDate())
            .equalTo("hours", workday.getHours())
            .equalTo("minutes", workday.getMinutes())
            .findFirst();

    System.out.println("--------------------------------");
    System.out.println(workday1.getHours());

回答1:

You are trying to remove an object you have not committed to the Realm yet.

In this particular case, if for some reason you don't want to commit the object anymore, you can simply cancel the transaction.

回答2:

In my case, the problem was that the same Object I was deleting was in an Adapter. After I made the Adapter extend RealmBaseAdapter the problem stopped.
