Persisting objects with Realm (error: Changing Realm data can only be done from inside a transaction)
<p>I am having difficulties getting Realm to work.</p>

<pre><code>RealmConfiguration realmConfig = new RealmConfiguration.Builder(this).build();
Realm.setDefaultConfiguration(realmConfig);
Realm realm = Realm.getDefaultInstance();

MyObjectExtendingRealmObject myObject = new MyObjectExtendingRealmObject("John");
realm.beginTransaction();
realm.copyToRealm(myObject);
realm.commitTransaction();
</code></pre>

<p>Error:  java.lang.IllegalStateException: Changing Realm data can only be done from inside a transaction</p>

<p>Call me crazy but aren't I doing the data persistence inside the transaction, which is exactly how it's done in the docs? See the example using <code>copyToRealm</code> here: <a href="https://realm.io/docs/java/latest/#creating-objects" rel="noreferrer">https://realm.io/docs/java/latest/#creating-objects</a></p>

<p>What am I doing wrong?</p>

<p>Edit: What, Realm doesn't support autoincrementing primary key ids? Dealbreaker for me. I'll leave this question up in case it helps others though.</p>

<p>Edit: My class</p>

<pre><code>public class MyObjectExtendingRealmObject extends RealmObject {
    private String name;

    public MyObjectExtendingRealmObject() {

    }

    public MyObjectExtendingRealmObject(String name) {
        this.name = name;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

}
</code></pre>
