Re: EOGenerator and prototypes

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:
<$foreach Attribute [EMAIL PROTECTED] do$><$if Attribute.userInfo.ERXConstantClassName.length > 0$> 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<$foreach Attribute [EMAIL PROTECTED] do$><$if ! Attribute.allowsNull$>, <$if Attribute.userInfo.ERXConstantClassName.length > 0$>< $Attribute.userInfo.ERXConstantClassName$><$else$><$

    return eoObject;

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,
