Hi Janak

Thanks for the help. I managed to build the event handler using the example in 
section 4.3 of the Extensions guide. I did have problems that it was searching 
for methods from the super class (in my case the ULCTextField) that didn't 
exist in my class. I then changed my dispatcher to to be a subclass of 
ULCTextFieldDispatcher instead of the ULCProxyDispatcher and everything was 
working fine. 

I am now having some strange experiences with the value change listener on the 
text field! It fires a valueChanged event when the value changes but when I get 
the value frmo the event source it returns me null for the first time the event 
fires (although I enter a value) and then each time the event fires, it sends 
me the first value entered. The value never changes!

Yes I am still working for Ottomobil and also building the framework privately 
for my own company
