A Trigger to extract key value pairs from a pipe delimited text file
This Trigger is incomplete. I just wanted to keep it for nostalgic purposes as it's the most complex/annoying one I've worked on so far.
I had a requirement to break down a field called Key Event String into a list of values. Then, to loop through the values searching for specific terms and adding up the totals for each.
It all sounded so simple but this particular trigger kept bringing up totals from one value and listing them against another. So Custom State 1 would actually be the total of Custom State 2.
I spent hours debugging but eventually decided to rewrite it. I'm pretty sure the answer lay where I was setting the value variable but rewriting gave me an opportunity to tidy it up and move the handling into a class.
So, here's the original trigger for posterity, but I'll be back with a (hopefully) fully functional one.
