Maybe a better solution is to provide default values as empty/null strings in
the action bean's property.
So if your property look like
private List<String> messages;
Try adding an initialisation method like
@Before(stages=LifecycleStage.BindingAndValidation)
public void populateDefaultMessages() {
messages = new ArrayList<String>();
for (int i = 0; i < 7; i++) {
messages.add("");
}
}
In your JSP, use indexed input fields like <stripes:textarea
name="messages[1]"/>
Remember that empty textarea will be replaced by null (default behaviour). But
I think you will still have an array of 7 elements.

Hi,
TypeConverter is for converting each value.
You need to write a custom ActionBeanPropertyBinder.
I wouldn't call it an easy way, but take a look at the default
implementation (DefaultActionBeanPropertyBinder) and see if you could
extend/override the default behavior.

Iwao
