Hi Prasanta,
I sent you two snippets.
The First: modification of your UIExtendedTable
-------------------------------------------------
In this we modified the UIExtendedTable class to have a method that sets
custom table header. We call this method from restoreState() initially. We
also want to invoke this method after we do fireTableStructureChanged() on
the server side. So to invoke this method on the client side from the server
we need to send a message from the server to the client. This we do in the
ULCExtendedTable.setCustomHeader() method where we send a message
sendUI("setCustomHeaders"). On the client-side in UIExtendedTable you need
to handle this message so we override UITable's handleRequest method and
check if message is setCustomHeaders then call setCustomHeaders() method.
Make sure that you separate out the client and server side classes when you
run your ULC client and ULC app in different JVMs e.g. as in jnlp & servlet
mode.
ULCExtendedTable should be on the class path of your server side ULC
application. Its typeString() method should return the fully qualified class
name of UIExtendedTable class:
"com.hp.gdic.scmas.ulc.util.model.authorized.SCMASTable.UIExtendedTable"
UIExtendedTable should be on the class path of your ULC client.
The second: Using ULCLabel as HeaderRenderer and setting multiline text on
it by using HTML
----------------------------------------------------------------------------
---------------
Can you tell me why is this solution not acceptable to you?
I hope this helps.
Thanks and regards,
Janak
