B4J Question How to force CheckBoxCombo to sequence your selection?

I don't think it is possible, looking at the java code for CheckComboBoxSkin, it simple reads the items from 0 .. n, if they are set it adds to the text using a StringBuilder.

i not like this comboboxes, its better to have a textfield + button and at button click you do something.
open a form with search/filter/(multi)select etc. and at close you write it as you wish info your textfield.
for the list you can use a TableView and for the data a Type Item(Checked,SortNo,Name)

other idea with CheckBoxCombo is to rename the list item with [1] at checked in changed event
and start .Sort but this will confuse the user.

or you need to compare the GetCheckedIndices before/after changed and build your own selection order list

Following @MarkusR advise, I ended up using a ListSelectionView which actually sorted out my issues. This is a far more perfect solution. CheckCombo removed. Ta!
