Martin,
The generated code does this
public BookCategory createBookCategoryFromString(EDataType
eDataType, String initialValue)
{
BookCategory result = BookCategory.get(initialValue);
if (result == null) throw new IllegalArgumentException("The
value '" + initialValue + "' is not a valid enumerator of '" +
eDataType.getName() + "'");
return result;
}
To support nillable elements in XML Schema, we also generate another
wrapper data type that allows null (since EEnum-based feature never
return null) and the method for that looks like this
public BookCategory createBookCategoryObjectFromString(EDataType
eDataType, String initialValue)
{
return
createBookCategoryFromString(LibraryPackage.Literals.BOOK_CA TEGORY,
initialValue);
}
So a null value for EEum-based feature would always serialize an xsi:nil
and we'd make no attempt to convert a null string value to a literal of
that type, we'd just set the feature's value to null. So maybe this
deep copy method should guard against creating an instance from a null
string value...

The indirection through PeriodObject is to allow Exchange.period to be

correctly, but disallows having a null period.
<br>
<br>
It looks like Teneo is ignoring the PeriodObject and just dealing with
the Period enum which can not be null.
<br>
<br>
Is there a way to get Teneo to save a null enum reference correctly?

Martin,
The generated code does this
public BookCategory createBookCategoryFromString(EDataType
eDataType, String initialValue)
{
BookCategory result = BookCategory.get(initialValue);
if (result == null) throw new IllegalArgumentException("The
value '" + initialValue + "' is not a valid enumerator of '" +
eDataType.getName() + "'");
return result;
}
To support nillable elements in XML Schema, we also generate another
wrapper data type that allows null (since EEnum-based feature never
return null) and the method for that looks like this
public BookCategory createBookCategoryObjectFromString(EDataType
eDataType, String initialValue)
{
return
createBookCategoryFromString(LibraryPackage.Literals.BOOK_CA TEGORY,
initialValue);
}
So a null value for EEum-based feature would always serialize an xsi:nil
and we'd make no attempt to convert a null string value to a literal of
that type, we'd just set the feature's value to null. So maybe this
deep copy method should guard against creating an instance from a null
string value...

The generated code does this<br>
<blockquote><small> public BookCategory
createBookCategoryFromString(EDataType eDataType, String initialValue)</small><br>
<small> {</small><br>
<small> BookCategory result = BookCategory.get(initialValue);</small><br>
<small> if (result == null) throw new
IllegalArgumentException("The value '" + initialValue + "' is not a
valid enumerator of '" + eDataType.getName() + "'");</small><br>
<small> return result;</small><br>
<small> }</small><br>
</blockquote>
<br>
To support nillable elements in XML Schema, we also generate another
wrapper data type that allows null (since EEnum-based feature never
return null) and the method for that looks like this<br>
<blockquote><small> public BookCategory
createBookCategoryObjectFromString(EDataType eDataType, String
initialValue)<br>
{<br>
return
createBookCategoryFromString(LibraryPackage.Literals.BOOK_CA TEGORY,
initialValue);<br>
}</small><br>
</blockquote>
So a null value for EEum-based feature would always serialize an
xsi:nil and we'd make no attempt to convert a null string value to a
literal of that type, we'd just set the feature's value to null. So
maybe this deep copy method should guard against creating an instance
from a null string value...<br>

Jeff,
<br>
Teneo tries to translate the PeriodObject to a string, to do this it
also touches the underlying Period enum. Afaics you should change the
JiemFactoryImpl.createPeriodFromString to handle null values to solve
this.
<br>
<br>
For my curiosity why does directly using the enum disallow null values?

<br>
The indirection through PeriodObject is to allow Exchange.period to be
set to null. Pointing Exchange.period directly to Period saves
correctly, but disallows having a null period.
<br>
<br>
It looks like Teneo is ignoring the PeriodObject and just dealing with
the Period enum which can not be null.
<br>
<br>
Is there a way to get Teneo to save a null enum reference correctly?
