Rick,
You should be able to do this in the indexed setter, something like this....
protected String[] myStringArray;
public void setMyString(int index, String myString) {
// Allocate the array
if (myStringArray == null) {
myStringArray = new String[index + 1];
}
// Grow the array
if (index >= myStringArray.length) {
String[] newMyStringArray = new String[index + 1];
System.arraycopy(myStringArray, 0, newMyStringArray , 0,
myStringArray.length);
myStringArray = newMyStringArray ;
}
// Set the indexed property
myStringArray[index] = myString;
}
Alternatively, just use a LazyValidatorForm and define the String[] as a
property in the struts-config and it will do this for you.
