java.lang.ClassCastException org.eclipse.emf.ecore.util.EcoreEList$Dynamic incompatible with commonj.sdo.DataObject

[Christian Landbo Frederiksen <Ch...@ementor.dk>]

Hi 
 
I just ran into a classcast exception when I tried to call getList on a
dataobject.
 
I searched a bit for it and found this in the samples:
 
PurchaseOrderControl.removeItem(int index) {
        // TODO: this is not working due to
java.lang.ClassCastException:
        // org.eclipse.emf.ecore.util.EcoreEList$Dynamic incompatible
with commonj.sdo.DataObject
        // access a DataObject by the index and then remove it
 
 
Can anybody tell more about this?
 
/Chr

I'm guessing that the property that your calling getList() for is single 
valued. You can only call getList() on a property if the property has 
Property.isMany == true. In other words, there's no automatic conversion 
from a single valued property value to List.
