Hi Team,
I have created an enterprise object with one-to-many relationship objects
associating. Then in the search page searched for these enterprise objects
(that has WODisplayGroup), I am able to view the newly created object, but when
I try to select that object to view the details it is generating the following
exception. If I restart the application then I am able to view the details of
the newly created object without any error, or If we try accessing the newly
created object after sometime (around half an hour later) then without error
able to view the object details. Otherwise the enterprise object is getting
null.
This enterprise object's super class has the database table, and this object
does not has the database table, it points to the same database table of the
super class. And the to-many relationship is existing with this enterprise
object (sub-class), not the super class.
Any help would be appreciated.
