ADF 11g : What is the Currently Active Taskflow in a Dynamic Region ?
2There are use cases in which you need to determine what the currently active taskflow is. This looks like simple, but in fact it is not ! Let’s rephrase that : Depending on the context, it can be a pretty confusing task. (more…)

This application uses ADF-Business Components and an Oracle Database. My first idea was to use database triggers for all tables (insert, delete, update for each row) and write the data to a log table. However that was not generic enough because this has to be implemented on every new table. I had to come up with an ADF solution. It’s basic, no rocket science, but useful (more…)
