Thank you so much for this. I am currently struggling with writing a before update trigger handler that updates fields of an SObject. Any suggestions?
Do you have any videos (or recommend any) for people who want to learn about triggers through the “Table-Driven Trigger Management” (TDTM) feature from the managed packages EDA or NPSP?
47:30 what to do if a managed package has 2 triggers on an object and we want to create our own trigger implementation? 🤔
Matt, you going to DreamForce this year? Hope to see you there. Great content sir.
I had intended too, but they scheduled it over my wedding, so maybe next year!
Congratulations on the wedding. I guess that’s a bit more important.
