struts and property=array

I am a little confused on how to use arrays within an Form object.

If I access the form object like <html:text property="myArray[0]"/> if the
object is null the page doesn't display correctly? Am I access the property
incorrectly? Or do I need to change the getter method? Currently the getter
methods for the arrays just return the arrays themselfs

ie

public String[] getMyArray(){
return myArray;
}

See if this helps:

Since you said you have a problem when the array is null, try making sure
that doesn't happen. Maybe
String[] myArray = new String[0];
if you don't have that in the form bean already.

If you're still stuck, post the exact error message you're getting so we
don't have to guess.
