I have a jsp page with a form on it using indexed properties. I have a bean
with an array of beans that I use to connect with the jsp page. The page
displays fine, but when I try to save it, I get the following error:

com.mysite.bean.SoldProperty.getExclusiveSold(SoldProperty.java:573)
Here is the relevant code:
protected SoldProperty[] ExclusiveSold;

/**

}
/**

And the jsp code:

Any ideas why I'm getting this error? And how to fix it?
Thanks,
