AutoCompleteDecorator does not work if a character is removed

[gillesB]

If a character is entered in the textfield of a combobox which is decorated with a SwingX AutoCompleteDecorator then an element from that combobox gets automatically selected.

This can be shown in the WuNDa Baulast Search.
Entered String: "Absta"
Found Element: Abstandsfläche

Unfortunately this does not work if a character is removed from that combobox.

String in the Textfield: "Abstandflächen"
The last n gets removed so that the String is: "Abstandsfläche"
But the element Abstandsfläche is not selected, this can be seen in the following screenshot.

This behavior is not dramatically but confusing for the user, because the element Abstandsfläche seems to be selected but in reality the String "Abstandsfläche" gets returned as selected object, and therefor the Baulast search does not work as expected.

I'm having a similar issue, but in my case, when you delete what you've previously typed, the previously typed default selection stays selected. If the user were to hit return, they end up with a selection that is not what they typed (when you include the deletion).
