(no subject)

Hello Janak

I have found the cause of my error. I still had a method in my class 
(updateValue) which shouldn't have been there. I put it there when I was 
getting the errors due to the Dispatcher problem and forgot to remove it.

Thanks for you help


ULC Extension Guide for ULC 6.1 has an example of creating ActionEvent on
the Pie Chart widget.

Nevertheless, I have created a small snippet for you which can be found at
the end of this mail.

Thanks and regards,

Janak

PS: Are you still developing for Ottomobil?
