I'm using APEX 23.1. I have a master table linked from a report to a form. I added an interactive grid to this form. I also replaced the automatic row processing with
1. api call
2. plugins
In both cases I get the error message
Process xxx has invalid (non Multi-row) Editable Region assigned.
Since each process has been assigned to the appropriate region and this works perfectly on pages with only one region, it looks more like a bug.
It would be nice if the APEX folks could analyze this.
Of course I would also be grateful for a tip
