It is my understanding that for indexed properties to work, you need to
have an additional method:
public void setLocationList(int index, ChildForm form) {
this.locationList.set(index, form);
}
This is because the nested tags produce indexed elements in the form:
<input type="text" name="locationList[0]" value="" />
<input type="text" name="locationList[1]" value="" />
... etc.
The only way I got this to work was to populate the array with empty
forms, and then the setLocationList(int, form) replaced the empty ones
with the correct ones. As I said earlier, this seems silly to me and
their should be an easier way. I spent about a day on this trying all
kinds of different approaches, and this was the only one I could get to
work.
