Hi Bhanu,
There are no standard methods available to have a single message per context node i.e. single message for all instances of context elements inside the context node.
We can have one message per context element of context node but cannot have single message for many context elements.
You cannot highlight the attributes of many context elements and link these to single message related to this.
If your requirement is to validate each row of a table and identify the attributes and display error message?
The per line, you can have a message.
Regards,
Rama
