you need to have an instantiated array of wrapper[] that is big enough
to take what your HTML submits. If your action form is in the request,
then wrappers[] will be null unless you instantiate it.

I've a problem with indexed properties inside an iteration. Some of the
properties are rendered as a text-area and should be editable by the
user. The rendering goes fine but if the user makes some changes, they
are not committed to the form. Please take a look at the jsp/html/java
snippets below.

this.wrappers = wrappers;
}
public GameTipWrapper getWrapper(int index) {
return wrappers[index];
}
public void setWrapper(int index, GameTipWrapper wrapper) {
wrappers[index] = wrapper;
}
