131. Can you create sharing rules for detail objects?

Ans - No. Detail objects cannot have sharing rules as the detail objects do not have owner field with them.

132. How can view state error be avoided?

Ans - Use transient keyword with variables wherever possible, clear unused collections. Use 1 form tag in a visualforce page.

133.Consider that a record meets a workflow criteria for time based workflow action, the action goes in queue . Later, before the time based action is triggered, the same record gets modified and the criteria previously met is changed and now it does not meet the workflow criteria, what happens to the time based action placed in queue?

Ans - The time based workflow action is removed from the queue and will not get fired.

134. What is the use of writing sharing rules?

Console tab fields and related list on the right hand side are also controlled by mini page layout.
