Back To FAQ's
What will happen when we write triggers such that objects update each other?
Circular updates should be avoided. Current version does not validate this scenario, hence developers have to ensure that there are no circular references.
What is the advantage of repost utility?
• Repost helps in iterative development by auto population of data in descendent objects
• Repost can be used for 'what if' analysis
• Back up of transaction data does not include data in descendent objects, thereby reducing storage space
Is the sequence of objects in Repost list important?
Yes. Ensure that all the objects with non-persistent triggers are listed first in a specific order, followed by Objects with persistent triggers. The order of objects varies according to application functionality. However, objects with persistent triggers can be listed in any order.
Can we write triggers that are chained like A updates B and B Updates C?
No. Limit trigger updates to a single level. “A updates B and A updates C” instead of “A updates B and B updates C.”
What is the difference between persistent and non-persistent trigger?
Please refer to session 8 of Vaakya tutorial for a detailed explanation.
