Hi Oliver,
use the "validateKey" mechanism (where "Key" is the name of property, e.g.
myNumber)
public Object validateMyNumber(Object aValue) throws
NSValidation.ValidationException {
// 1. cast aValue to int (or whatever you need
// 2. write check method, e.g. SOMETHINGWRONGWITH_aValue
// throw exception, if aValue is not what you want it to be
if (SOMETHINGWRONGWITH_aValue) {
throw new NSValidation.ValidationException(aValue+" is
not allowed for property 'MyNumber');
}
}
This method will be called by WO automatically before the settermethod
setMyNumber is called.
Or you overwrite "validateForSave" or "validateForUpdate" in your entity's
class (which should be a subclass of EOCustomObject).
For more basic information see:

or the documentation of NSValidation
http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/foundation/NSValidation.html
or the documentation of EOCustomObject
http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/eocontrol/EOCustomObject.html#validateForUpdate()
Hope, this helps ...
