It does not, by default, generate the correct subclass because I believe EO doesn't give back anything but Number. Here's is the workaround from a discussion thread a while back:

<$foreach Attribute classAttributes.@sortedNameArray do$><$if Attribute.userInfo.ERXConstantClassName.length > 0$> public <$Attribute.userInfo.ERXConstantClassName$> <$Attribute.name $>() { Number value = (Number)storedValueForKey("<$Attribute.name$>"); return (<$Attribute.userInfo.ERXConstantClassName$>)value; }

public void set<$Attribute.name.initialCapitalString$>(< $Attribute.userInfo.ERXConstantClassName$> aValue) { takeStoredValueForKey(aValue, "<$Attribute.name$>"); } <$else$><$ identify currentValueType = Attribute.javaValueClassName$><$ if currentValueType == 'Number'$><$ if Attribute.valueType == 'B'$><$ identify currentValueType = 'BigDecimal'$><$ elseif Attribute.valueType == 'b'$><$ identify currentValueType = 'Byte'$><$ elseif Attribute.valueType == 'd'$><$ identify currentValueType = 'Double'$><$ elseif Attribute.valueType == 'f'$><$ identify currentValueType = 'Float'$><$ elseif Attribute.valueType == 'i'$><$ identify currentValueType = 'Integer'$><$ elseif Attribute.valueType == 'l'$><$ identify currentValueType = 'Long'$><$ elseif Attribute.valueType == 's'$><$ identify currentValueType = 'Short'$><$ endif$><$ endif$> public <$currentValueType$> <$Attribute.name$>() { return (<$currentValueType$>) storedValueForKey("<$Attribute.name $>"); }

public void set<$Attribute.name.initialCapitalString$>(< $currentValueType$> aValue) { if (<$GEN_PREFIX$><$classNameWithoutPackage$>.LOG.isDebugEnabled ()) { <$GEN_PREFIX$><$classNameWithoutPackage$>.LOG.debug( "updating <$Attribute.name$> from "+<$Attribute.name$>()+" to "+aValue ); } takeStoredValueForKey(aValue, "<$Attribute.name$>"); } <$endif$>

and the same thing in the .createXxx "constructor" functions that I use:

public static <$classNameWithoutPackage$> create< $classNameWithoutPackage$>(EOEditingContext editingContext<$foreach Attribute classAttributes.@sortedNameArray do$><$if ! Attribute.allowsNull$>, <$if Attribute.userInfo.ERXConstantClassName.length > 0$>< $Attribute.userInfo.ERXConstantClassName$><$else$><$ identify currentValueType = Attribute.javaValueClassName$><$ if currentValueType == 'Number'$><$ if Attribute.valueType == 'B'$><$ identify currentValueType = 'BigDecimal'$><$ elseif Attribute.valueType == 'b'$><$ identify currentValueType = 'Byte'$><$ elseif Attribute.valueType == 'd'$><$ identify currentValueType = 'Double'$><$ elseif Attribute.valueType == 'f'$><$ identify currentValueType = 'Float'$><$ elseif Attribute.valueType == 'i'$><$ identify currentValueType = 'Integer'$><$ elseif Attribute.valueType == 'l'$><$ identify currentValueType = 'Long'$><$ elseif Attribute.valueType == 's'$><$ identify currentValueType = 'Short'$><$ endif$><$ endif$><$currentValueType$><$endif$> <$Attribute.name$><$endif$>< $endforeach do$><$foreach Attribute parentEntity.classAttributes.@sortedNameArray do$><$if !

Hi there,
I've just reworked a model to utilise a prototypes model - but when eogenerating the classes I'm finding that I'm no longer getting BigDecimal, for example, in the signature but Number instead.
e.g.,
// template snippet... public <$Attribute.javaValueClassName$> <$Attribute.name$>() { return ( <$Attribute.javaValueClassName$> )storedValueForKey( < $Attribute.name.initialCapitalString$>Key ); }
// is producing something like:
public Number name() {
	return ( Number )storedValueForKey( NameKey );
}
Example prototype:
MyPrototypes.eomodeld/
EOJDBCMySQLPrototypes.plist
<...>
       {
           allowsNull = Y;
           columnName = "";
           externalType = NUMERIC;
           name = "decimal(14,2)";
           precision = 14;
           scale = 2;
           valueClassName = NSNumber;
           valueType = B;
       },
<...>
Any ideas?
with regards,
