How to pass value into Listener in selectOneMenu

Question

I have 2 dropdowns: Type & Code. I want the Code dropdown to change values depending on the Type dropdown if value = A or B or C. How can I pass value of A or B or C into listener so it can understand and process my List ? ``` ```

Accepted Answer

remove the `event="valueChange"` from your `<f:ajax` or replace it with `event="change"`

You don't have to pass the value as its already there (in `changeCodeList` method)

```
public void changeCodeList(AjaxBehaviorEvent ev) {
    System.out.println(type); //here is your value
    //now repopulate your list based on the value
    codeList = someMethod(type);
}
```
