I've got a simple option class (as i've seen in examples)<p/>
public class Option {
String key;
String value;
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public Option(String key, String value) {
this.key = key;
this.value = value;
}
}
I then populate an ArrayList (called imageList) with several entries of the
Option class.<p/>
Then I add a dropdownchoice component to my form using:
ChoiceRenderer choiceRenderer = new ChoiceRenderer("value", "key");
form.add(dropDownChoice = new DropDownChoice("imageCollectionId",
imageList, choiceRenderer));
This works fine to display the key and value bits correctly in the html, but
then how do I get out the key and value properties.
The only way I've found so far is to have the imageCollectionId attribute in
my POJO business object of type Option, whereas I only want it to be of type
String - where it should just hold the 'key' value of the Option class.
All I want is to get at the 'key' value, but display the 'value' on the
screen.
Hope that makes some sense, it's been puzzling me all day, and I thought it
would be so simple.
Cheers
