Hi,
I am debugging for CDO-Teneo and found that when calling EAttribute.getDefaultValue() for an EAttribute with upperbound
-1 and EDataType int that a value of Integer 0 is returned. I am wondering is this correct/intended behavior?
I myself would expect a null value.

Martin,

I suppose this code should be checking that feature is single valued:

public Object getDefaultValue()
{
EClassifier eType = getEType();
String literal = getDefaultValueLiteral();

if (literal == null && eType != null)
{
return eType.getDefaultValue();
}
