[Databinding] Put data to a WritableMap from other Thread [message #1018151]

Hello,

I do like to put data into a org.eclipse.core.databinding.observable.map.WritableMap from another Thread, but the checkRealm() method throws an AssertionFailedException Exception with the Message "This operation must be run within the observable's realm", because the current Realm of the WritableMap is not used.

So I tried to use Realm.getDefault().asyncExec(), but then Realm.getDefault() just returns null and causes an NPE Sad

Do you have an idea how databinding and multithreading can be combined?

Best regards,

Simon

You need to get the realm from the WritableMap!
