/**
|
| 51 |
* This class inherits of 'AbstractDefaultComboBoxItemsSeekerConfigurableModel' and can be used with repeated items or not. If there aren't
|
| 52 |
* repeated items this model works worse than 'ComboBoxSingularItemsSeekerConfigurableModel', and it's recommended use it.
|
| 53 |
* It's probably that this model work slow, more when more items had.
|
| 54 |
*
|
| 55 |
* Limitations: This model works slowly if has a lot of items, and if no item is repeated works much worse than using 'ComboBoxSingularItemsSeekerConfigurableModel':
|
| 56 |
* needs more time.
