Subset table not updating

[#1]

I keep receiving this error when trying to add a new entry to my source table. When I created the subset tables I selected "link to original table" so I'm not sure what the issue is.

JMP 19

Unfortunately, some actions are not possible in JMP (v19).
Similar issues for sorting and concatenate.

To get the issue fixed, please follow the link and vote:

Sort data table + add rows + concatenate -- make it possible 

fun  facts:

- instead of sorting a table, one can create a dummy, sorted table and then paste the data from the dummy table into the main table.
- Deleting a row is possible, adding a row is not possible.
