Getting lists back from struts

Question

I have encountered this issue a couple of times, always found a way to code around but now I really need to ask:

Can struts create lists/arrays (or whatever collection) when e.g. using

public class MyAction extends ActionSupport {
 public List getChoices() {
 ....
 }
 ....
 public List getPreSelectedChoices() {
 // returns a list of Choice.getKey(), which is a String
 ....
 }
 }

 public class Choice {
 public String getKey() { ...}
 public String getDisplayName() { ... }
 ....
 }

The selected values are sent to

public void setMyChoice(String myChoice){
 ...
}

correct? There is no way something like

public void setMyChoice(String[] myChoice){
 ...
}

works in struts?

If not, whats the common way to get the values back from the String myChoice? Use Split on it?
