I have a selectable grid (only one row can be selected). When an item is selected, it is bound to a form for editing. Textbox in the form has a custom binding 'valueInput'. If I select a several different items from a grid and then try to edit current selection in the form, all previosuly selected items are modified. If I change binding to built-in 'value' then it works fine (only last selected item gets modified). How to fix it ?
How get the incorrect behavior:
1. Select an element from grid.
2. Select another element from grid.
3. Modify textbox value.
4. All previously selected items will change.
