Getting lists back from struts

2013-08-07 Thread Fabian Richter 

Hi

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 ListChoice getChoices() {
 
  }
  
  public ListString getPreSelectedChoices() {
 // returns a list of Choice.getKey(), which is a String
 
  }
 }

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

 ww:checkboxlist name=myChoice
  list=%{choices}
  listKey=%{'key'}
  listValue=%{'displayName'}
  value=%{preSelectedChoices} /

The selected values are sent to

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

correct? There is no way somthing 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?


Thank you!

Best
Fabian
