java - ComboBoxTableCell JavaFX -

i have class arraylist of localdate

public class item {     private arraylist<localdate> dates; } 

and tablecolumn in class

observablelist<item> itemobservablelist = fxcollections.observablearraylist(); tablecolumn<item, localdate> datescolumn = new tablecolumn<>("dates"); datescolumn.setcellfactory(param -> new comboboxtablecell<>()); 

i figured how set cellvaluefactory column, want comboboxtablecell have values object of item class. every combobox should have it's own values based on item object.

you can @override comboboxtablecell's startedit() method this:

datescolumn.setcellfactory(param -> new comboboxtablecell<item,localdate>(){       @override public void startedit() {                 item item = (item)gettablerow().getitem();                 getitems().setall(item.getdates());                 super.startedit();         } }); 

so have dates in comboboxes each individual row item's dates. may define stringconverter<localdate> it.
