Description

Top-level DataContext fails to attach to default DataDomain transparently on deserialization.

Caused by: org.objectstyle.cayenne.CayenneRuntimeException: [v.1.2B2
April 17 2006] Cannot commit changes - channel is not set.
at org.objectstyle.cayenne.access.DataContext.flushToParent(DataContext.java:1186)
at org.objectstyle.cayenne.access.DataContext.commitChanges(DataContext.java:1121)

Data context is created with:

DataContext.getThreadDataContext().createDataContext()

Data context is serialized with:

private void writeObject(java.io.ObjectOutputStream out) throws IOException

{ out.writeObject(this.childDataContext); }

Data context is deserialized with:

private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException

{ this.childDataContext = (DataContext)in.readObject(); // childDataContext.setChannel(super.threadDataContext().getParentDataDomain()); }

Problem goes away if setChannel line is uncommented.
