Custom DOM sort and hiding columns

rsprinkle

I am using a custom sSortDataType to sort input:text fields in the table. I am using the example for dom-text from this site. That pretty much works as expected until I hide and then unhide the sorted column. Apparently DataTables take the data from the custom sort and inserts it into its backing store destroying the original data. Not intuitively obvious that sorting will erase data. Seems to me that the display cache and the sort cache, for a custom sort, should be separate elements. Any advice on how to overcome this limitation.
