Hi,

The error comes out when I do a drag and drop of component node from palette on to the editor, Nothing comes on the editor...


Thanks,
Vinay

Hi,

so it means that there is a condition that doesn't allow you to drop the component or there is an issue during the creation of the element. You can try to look into CreationEditPolicy.
