Hello. Java Beans allows for write-only bean properties (see chapter 8.3.1 of the Java Beans specification, 'Simple properties'). With class BeanMap it is possible to handle write-only properties as well.
On the other hand, the #keySet method of a BeanMap instance doesn't care about write-only properties, because the key set is computed from the internal set of read methods, and there is no read method for a write-only property. Moreover, the new value parameter of the protected method #firePropertyChange will always be null if write-only properties are involved, because the new value is computed by the use of the read method. The usage of write-only properties is very rare (e.g., see http://java.sun.com/products/javabeans/docs/getListeners_p.html) and I recommend to introduce a comment within methods like #keySet: "Write-only properties aren't included in the returned set of property names, although it is possible to set their value and to get their type." -Peter ______________________________________________________________________________ Belgien, Italien, Portugal,...
