Grid column data loading when User a ref entity

[masumcse1]

Problem : when a CET has a CFT of type user as reference of entity ,
on that time grid summary column data is not loaded .

Root cause :
For showing data on grid ,it used <f:converter binding="#{entityReferenceConverter}" /> converter when data type is reference entity.
In this case , this converter (EntityReferenceConverter.java ) did not return any value from db (table-adm_user).
as a result this column is showing wrong value.

solution :
If CFT type is User type. in case i retrieve data from database by uuid.
