Hi MArk,
Basically you want to send a message from the client to the server when
there is a problem on the client.
Which version of ULC are you using?
In ULC 6.1, you can call a method on the server side proxy from the client
side proxy using invokeULC() method.
So your client side code will look like:
if (error)
invokeULC(...);
}
Then on the serverside class you can implement a Dispatcher class which will
delegate the method call to a method in the server side class. In that
method you can send back the data by invoking a method on the client using
invokeUI(...).
Please read sections 3.4.1 & 3.4.2 of ULC Extension Guide.
I hope this helps.
Thanks and regards,
Janak
