Hi All,
I have searched and wasted much of my time figuring out the default Value for
DropDownChoice for Object as dropdown but couldn't find the solution. For
"String" dropdown i was able to make it work but somehow for object it is not
working.
Below is the Simple example that i have been trying, DropDownChoicePage.html
and DropDownChoicePage.java files.
Can someone please help me that what am i missing into
"DropDownChoicePage.java" class that is not setting the Drop Down Default
value?
----------------------------------------
DropDownChoicePage.html
<html xmlns="http://www.w3.org/1999/xhtml";><head> <title>DropDown
Example</title></head><body>
Select your favorite Language <select
wicket:id="languageDropDown"></select> </body></html>
---------------------------------------------------------------
DropDownChoicePage.java
public class DropDownChoicePage extends WebPage {
public class KeyValue {
private String key; private String value;
public KeyValue(String key, String value) {
this.key = key; this.value = value;
}
public String getKey() { return key;
}
public String getValue() { return
value; }
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>( "languageDropDown",
new PropertyModel<KeyValue>(this,
"defaultValue"), keyValues, new
ChoiceRenderer<KeyValue>("key", "value")); add(dropDownChoice);
}
public KeyValue getDefaultValue() { return
defaultValue; }
public void setDefaultValue(KeyValue defaultValue) {
this.defaultValue = defaultValue; }
}
Thanks, Vimal.
