Hi Jermey,
Thanks for your suggestion and it worked. I will remember you suggestion on
overriding equals and hashCode methods.
Just for any future reference for someone else i am putting the working
code.
public class DropDownChoicePage extends WebPage {
public class KeyValue implements IClusterable {
private static final long serialVersionUID =
4901576176376580786L;
private String key;
private String value;
public KeyValue(String key, String value) {
this.key = key;
this.value = value;
}
// Most important to override this method
@Override
public boolean equals(Object obj) {
KeyValue keyValueObj = (KeyValue) obj;
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
if (key.toString().equals(keyValueObj.toString()))
return true;
else if
(value.toString().equals(keyValueObj.toString()))
return true;
return false;
}
public String getKey() {
return key;
}
public String getValue() {
return value;
}
// Most important to override this method
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + key.hashCode();
result = prime * result + value.hashCode();
return result;
}
public void setKey(String key) {
this.key = key;
}
public void setValue(String value) {
this.value = value;
}
@Override
public String toString() {
return getKey();
}
}
private static final long serialVersionUID = 2304448232406333188L;
private KeyValue defaultValue = new KeyValue("JAVA", "Java");
/**
* Constructor
*/
public DropDownChoicePage() {
List<KeyValue> keyValues = new
ArrayList<DropDownChoicePage.KeyValue>();
keyValues.add(new KeyValue("PHP", "php"));
keyValues.add(new KeyValue("JAVA", "JAVA"));
keyValues.add(new KeyValue("DOT_NET", "Dot Net"));
DropDownChoice<KeyValue> dropDownChoice = new
DropDownChoice<KeyValue>(
"defaultValue", new
PropertyModel<KeyValue>(this,
"defaultValue"), keyValues,
new ChoiceRenderer<KeyValue>("value", "key"));
add(dropDownChoice);
}
public KeyValue getDefaultValue() {
return defaultValue;
}
public void setDefaultValue(KeyValue defaultValue) {
this.defaultValue = defaultValue;
}
}
Thanks,
Vimal.
