Is multifieldpanel deprecated in 6.3 Classic UI

[poornimab543386]

I have created mutlifield dialog in classic UI AEM 6.2 using fieldConfig widget (xtype=multifieldpanel).And it is working fine.

But I get error when I do the same in 6.3 classic UI.

Anyone please let me know why does this occur ! Or is this deprecated in 6.3 classic UI

Using Classic in AEM 6.3 is not best practice, You should be using Granite/Coral resource types. Building Experience Manager Components using Granite/Coral Resource Types
