java - SelectedItems empty if multiple rows selected using different columns -

i have tableview in selectionmode.multiple. using listchangelistener i'm able catch selection of multiple rows (by pressing shift).

however solution works if items being selected in same column or in area without columns. gif illustration 4 examples:

1. ok: selecting 3 items using shift in state column
2. ok: selecting 4 items using shift in idx column
3. ok: selecting 4 items using shift starting state column area without columns
4. error: trying select 4 items using shift starting state column data item column

the problem seems selecteditems-list apparently empty in last example. i'd appreciate regarding issue.

here approach:

observablelist<datarowmodel> datarows = fxcollections.observablearraylist(); datarows.addall(datasetmodel.getrows()); tabledatarow.setitems(datarows); tabledatarowstatecolumn.setcellvaluefactory(f -> f.getvalue().getstate());  tabledatarow.getselectionmodel().setselectionmode(selectionmode.multiple); tabledatarow.getselectionmodel().getselecteditems() .addlistener((listchangelistener.change<? extends datarowmodel> c) -> {     while (c.next()) {         c.getremoved().stream().foreach(remitem -> remitem.setselected(false));         c.getaddedsublist().stream().foreach(additem -> additem.setselected(true));         system.out.println(c.getlist()); //empty [] when selected using different columns     } }); 

just better understanding of code: setselected(...) sets booleanproperty on datarowmodel bound state-column.

without context reason using selected-property seems quite silly. however, there various other fragments of code changelisteners bound selected-property.
