Issue 61522

Use the following java code to create an additional attribute stored at the 
document (not you'll need jdk1.5 for it!).
After running the class (of course you have to ensure that the needed jars
are in the CLASSPATH) you'll see that the attribute was added to the document
but even setting the attribute of the property to BOUND and CONSTRAINED
don't lead into an event in case of a PropertyChange:

import com.sun.star.frame.*;
import com.sun.star.lang.*;
import com.sun.star.lang.EventObject;
import com.sun.star.uno.*;
import com.sun.star.uno.Exception;

public class Test {

	@SuppressWarnings("unchecked")
	public final static <T>T cast(Class<T> type, Object object) {
		return (T) UnoRuntime.queryInterface(type, object);
	}

	public static void main(String[] args) throws BootstrapException, 
Exception, InterruptedException {
