------------------------------------
Summary: Allow selected key bindings to work with unselected items
Key: PIVOT-948
URL: https://issues.apache.org/jira/browse/PIVOT-948
Project: Pivot
Issue Type: Bug
Components: wtk
Affects Versions: 2.0.3
Environment: All
Reporter: Roger Whitcomb
Assignee: Roger Whitcomb
Priority: Minor
Fix For: 2.1
Attachments: binding.patch
If you set a selected key binding (on a ListButton, ListView, TableView or
Spinner), and invoke the "store" method when no item is selected, you can get
an error about not being able to assign "null" to an "int" field (in my case).
The problem is that "store" tests for nothing being selected and sets the item
to null without even calling the binding method. In my case, I am using the
binding to just store the selected index as an integer, so the item will not
end up being null, except that the binding method is never called.
So, the item value to be stored should be left up to the binding method, even
in the "unselected" case in order to be consistent (and to allow my selected
index bind mapping to work correctly, even in the unselected case).
It will be more clear what the problem is when you see the patch file.
