ControlsFx - Spreadsheetview - DateCell - keep editing on failure - spreadsheet

Question

we use a spreadsheetview with different kind of cell types.
In the documentation to SpreadsheetCellEditor we found the following text:
The policy regarding validation of a given value is defined in
SpreadsheetCellType.match(Object). If the value doesn't meet the requirements
when saving the cell, nothing happens and the editor keeps editing.
now we facing the following problem:
if you enter "abcd" in an integer cell as a wrong entry and push enter key, nothing happens. Editor is still in edit mode. This is exactly the behaviour as descripted in the documentation. that is what we want.
if you have a date cell and enter a wrong date or something else and push enter key, cell stops editing mode and set value return to "old" value.
how can we prevent this behaviour?
Maybe its a bug in the Date SpreadsheetCellType?
we use a lot of custom cellType Classes, but the behaviour is also comprehensibly with this little example.
I hope everything is well explained.
Thanks for your help.

Answer 1

It is solved.
i got some help from one of the major contributor of ControlsFX.
The documentation was a bit unclearly.
In order to get the described behavior, a custom Cell Type + Editor based on the existing ones can be created.
For all details take a look in this thread:
