[CDO] custom EDataTypes [message #515302]

Thu, 18 February 2010 07:46

Hi all,

our model contains a Polygon object which holds a list of Point objects, which are
custom EDataType.
When I make a copy of the Point list with

List<Point> points= new ArrayList<Point>(polygon.getPoints());

ArrayList calls the collection's toArray() method and EMF/CDO returns list of Strings instead of a list of Point objects.

The strings are the result of convertPointToString() serializer method.

This causes some problems, e.g. because EMF EDIT's RemoveCommand also uses ArrayList to create a copy of the to be removed objects.

Thanks in advance

Rolf

Hi Rolf,

I think there's a bug in CDOStore's toArray() implementations. Please
file a bugzilla.

Cheers

I still have problems with custom EData Types when an EMF EDIT RemoveCommand
is invoked on a custom EDataType collection:

	at  org.eclipse.emf.cdo.spi.common.revision.BaseCDORevision.getList(BaseCDORevision.java:564)
	at  org.eclipse.emf.cdo.spi.common.revision.BaseCDORevision.contains(BaseCDORevision.java:428)
	at  org.eclipse.emf.internal.cdo.CDOStore.contains(CDOStore.java :247)
	at  org.eclipse.emf.ecore.impl.EStoreEObjectImpl$BasicEStoreEList.delegateContains(EStoreEObjectImpl.java:205)
	at  org.eclipse.emf.ecore.impl.EStoreEObjectImpl$BasicEStoreEList.delegateContainsAll(EStoreEObjectImpl.java:213)
	at  org.eclipse.emf.common.util.DelegatingEList.containsAll(DelegatingEList.java:125)
	at  org.eclipse.emf.edit.command.RemoveCommand.prepare(RemoveCommand.java:248)

getList() returns list of Strings instead of list of custom EDataType, thus containsAll returns false and the objects are not removed.

I use CDO 3.0 HEAD (fix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=303279 included)

Hi Rolf,

If you feel there's a bug somewhere in CDO, please just file a bugzilla.
You don't necessarily have to go through the newsgroup. I can not start
fixing something without a bugzilla.
