f:selectItems and List - managed property

[Brian Smith]

I am trying to use a managed property list-entries to initialize a List that an f:selectItems is bound to.

<f:selectItems value="#{RowsPerPage.rows}"/>

Here is the managed bean from faces-config

    <managed-bean>
        <managed-bean-name>RowsPerPage</managed-bean-name>
        <managed-bean-class>com.stlouiscity.jsf.util.RowsPerPage</managed-bean-class>
        <managed-bean-scope>none</managed-bean-scope>
        <managed-property>
            <property-name>rows</property-name>
            <property-class>java.util.ArrayList</property-class>
            <list-entries>
                <value-class>java.lang.Integer</value-class>
                <value>1</value>
                <value>5</value>
                <value>10</value>
                <value>25</value>
                <value>50</value>
                <value>100</value>            
            </list-entries>
        </managed-property>
    </managed-bean>

Here is the class

package com.stlouiscity.jsf.util;
import java.util.List;
public class RowsPerPage {
    private List rows;
    public RowsPerPage() {
    }
    public List getRows() {
        return rows;
    }
    public void setRows(List rows) {
        this.rows = rows;
    } 
}

Here is the stack trace

Show your UIInput JSF + bean code.

"BalusC",

There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

Thanks!

This was already changed afterwards. Probably the forum wasn't refreshed quick enough.

Thank you!

selectItems will look for a List of SelectItem objects. So you would need to have code that does something like:

rows.add(new SelectItem("Label", "Value"));
