When deleting both the parent and child at the same time (click on parent and do a delete row), during the processing of the rows there is a javascript error stating: “childNodes is null or not an object” and thus the getSynchState is always returning false. It works if I only delete a child row.
Which component does you question concern ?
Do you use DataProcessor functionality ?
Yes this is using the dataprocessor with the tree grid.
We was able to reconstruct similar issue in local samples.
Update which will resolve issue ( processing of updated childs in deleted branch ) will be released in few days as part of new release.
