Default Value for View Object Rows Attributes

Hi all,

Introduction

As usual in all programming tools we need to set default values for columns.
>>In oracle database we can do that by DDL
ALTER TABLE Table_name MODIFY(column_name  DEFAULT default_value);
>>In oracle forms tool we can do that by setting initial value of item in block.

We can do that by 3 ways
1-Using a Groovy expression
2-Getter of attribute
3-Override view object create() method
