We are upgrading from AEM 6.0 to AEM 6.4. We have some existing xtype which I am trying to implement in Touch UI.
Our existing data for multifield is stored as json
When I try to use the "granite/ui/components/coral/foundation/form/multifield"
It stores the data as Node structure in AEM 6.4.
Any help or pointers to the samples will be helpful.
There is acs commons widget available to store value as node as well as in json structure.
Please refer below article for step by step implementation.
Using the ACS AEM Commons Nested Multifield | Bounteous
Focus on "acs-commons-nested=JSON_STORE" property, it is working fine in 6.4 as well.
