I recently saved my entity from Lead to opportunity, and i thought once the entity is created i will use postimage to extract the data, then my colleague told me that just by using the entity as target from context all data can be accessed. I am unable to understand it, I know the concept of postimage and preimage, now here before create as there was no data so preimage don't exist and plugin preoperation if has any values that might be coming from lead.
How I am able to extract all the field columns on create from entity, as i am thinking it has not been created yet and as my operation is post so may be by that but then what's the use of postimage for oncreate?
