Salutation to everyne!
I have a form (extends ActionForm) that has a property "countriesList"
which holds a list of beans. In jsp form page I have a code:
<bean:define id="cl" name="userForm" property="countriesList"/>
which is executed without problems when the page is shown first time,
but when I click submit without entering values into textboxes,
"valiate" method of my "UserForm" works out and redirects the flaw
back to "user.jsp" and here I get exception. Looks like "countryList"
property vanishes from "userForm".
