'Magnolia detail subapp commit action
I'm on magnolia 6.2.15 and I need to generate data from some fields that users insert in a content detail subapp. I thought about creating a subclass of magnolia "SaveDetailSubAppAction", in the "execute" method to do the job. I can retrieve fields value but, how can I generate new fields data values and insert that in the form before validation and commit to jcr datasource?
