This has to be the strangest thing...

[Gregg Bolinger]

Ok, this is so strange because I swear this worked before and all of a sudden, it doesn't. I mean, it worked 2 days ago. And now it has stopped. I haven't changed anything.

If I declare the value of a selectonemenu as a String when I postback to the page, the dropdown contains the selected value. If I declare the value as an Integer, it defaults back to the first one in the list. Here is the example...

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<f:view>
<h:form>
<h:selectOneMenu value="#{testBean.choose}">
    <f:selectItems value="#{testBean.choices}"/>
</h:selectOneMenu>
<h:commandButton value="Push" action="#{testBean.doThis}"/>
</h:form>
</f:view>

public class TestBean {
 
    private Integer choose;
 
    public List getChoices(){
        ArrayList list = new ArrayList();
        list.add(new SelectItem("1", "Item 1"));
        list.add(new SelectItem("2", "Item"));
        return list;
    }
 
    public Integer getChoose() {
        return choose;
    }
 
    public void setChoose(Integer choose) {
        this.choose = choose;
    }
 
    public String doThis(){
        return "success";
    }
}

Now, if you go in and change the type for choose to String, it works. Otherwise it won't. I can probably use a converter if I need to or something, but I don't understand why 2 days ago it worked and now it doesn't. Can anyone else confirm that it does or does not work? I asummed JSF had auto conversion for basic types (Long, Integer, String, etc). I may be wrong and it may have been working all along when it really should'nt have.

Thanks.

private Object choose;          
new SelectItem(new Object(), "Item 1");

I am not sure, but I think the type (Integer, String) wouldn't matter unless these two Objects are of same type.

Are you getting the error while submitting the page?

Try add <h:messages> on your page :-)

You should either use

list.add(new SelectItem([B]new Integer(1)[/B], "Item 1"));
private Integer choose;

or

list.add(new SelectItem([B]"1"[/B], "Item 1"));
private String choose;

Yeah, that was it. I need sleep.
