The type of page the module holds.
- ie List of records, New record, URL etc.
When creating a new UI policy, what do you need to first do before you can add actions?
Save the new record

- Script
What 3 behaviors can be controlled via a UI Policy?

What does the “Global” checkbox on a UI policy do?
When true, it applies to all views for that table.
What is the default value for the UI Policy “On load” field?
The course says “The onLoad checkbox deals with whether this UI policy should execute when the form is loaded. The default behavior for a UI policy is to execute when the user makes a manual change to a field on a form. If we do want this to be evaluated also when the form is loaded, we would need to check the onLoad checkbox”
This isn’t true at least from what I can tell in our instance. When I went to create a new UI policy, the onLoad field was checked. When I looked at its dictionary entry, its default value is true.
Would you need a UI policy or client script to keep track of a fields prior value?
Client script.
Which executes first: UI policies or client scripts?
Client scripts
What is the syntax for setting a display business rule scratchpad variable?
g_scratchpad.var1 = current.field1;

What is recommended if you are looking to incorporate security into scripts, outside of ACL’s? Why?
Use server-side scripts, specifically the GlideSystem and GlideRecord methods. Server side scripts are more performant and more secure.
What happens if you have a script in one application scope that deletes records but the caller application does not have delete access?
What if the script also contains an insert and the caller application DOES have access?
