Question 324

There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user.

The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, *Maximum view state size limit exceeded.

What step should the developer take to resolve this issue?

Split the layout to filter records in one Visualforce page and display the list of records in a second page using the same Apex Controller.

Adjust any code that filters by picklist values since they are not indexed.

Use a StandardSetController or SOQL LIMIT in the Apex controller to limit the number of records displayed at a time.

Remove instances of the transient keyword from the Apex controller to avoid the view state error.

Question 328

Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer. Recently a workflow rule was added so that whenever an Account is marked as a Customer, a 'Customer

Since' date field is updated with today's date.

Since the addition of the workflow rule, two Account Plan records are created whenever the Account is marked as a Customer.

What might cause this to happen?

The workflow rule is configured to evaluate when a record is created and every time it is edited.

The workflow rule field update is marked as 'Re-evaluate Workflow Rules After Field Change."

The Apex trigger does not use a static variable to ensure it only fires once.

The Apex trigger is not bulk safe and calls insert inside of a for loop.
