[JIRA] Created: (CAY-553) Top-level DataContext fails to attach to

Top-level DataContext fails to attach to default DataDomain transparently on deserialization
--------------------------------------------------------------------------------------------
Key: CAY-553
URL: http://issues.apache.org/cayenne/browse/CAY-553
Project: Cayenne
Type: Bug
Components: Cayenne Core Library
Versions: 1.2 [BETA]
Reporter: Mike Kienenberger
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.
