Alter entity column size or type

[Raj Saini]

Hi,

Is there a way to extend the field  type of a entity using extend-entity 
or any other similar mechanism without modifying the original entity 
definition. I tried using extend-entity by redefining the exiting field 
with a different data type, but it added a new column to the database 
table instead of altering it.

Thanks,

Raj
