I've been asked by my company to learn Trigger Development for IBM® OpenPages® GRC Framework.
I have read the Trigger Developer Guide provided by IBM. But it is more focused on only concepts but does not tell how to start (meaning setting a Development Environment).
I have no idea where to start and there is no help on the internet. Any help how should I start learning trigger development.
I was trained in my company from an IBM consultant about IBM® OpenPages® GRC Framework. However, it seems to me that there are at this point in time no "free/open" guides available.
One of the "open" guides is the paper you already pointed out. However, IBM provides a lot of trainings and also support for the IBM® OpenPages® GRC Framework, therefore I would suggest you contact, their customer support or ask in your company about to get training on this framework.
Hope I could help!
BR.
