Hi James,
Those methods were never a part of the official API, but by logging the results in this demo https://jsfiddle.net/ubx0jy39/ I think that
getPlugin('nestedRows').dataManager.data
should be the same as getSettings().data
, and hot.getPlugin('nestedRows').dataManager.cache.rows
gives us the same result as getSourceData()
. Here’s a demo with v12.3.x https://jsfiddle.net/dcoe1qtm/1/
Would that meet your requirements?
