Hi memberhieu,

I hope you must have already overcome this issue but still wanted to post something to help others.

This error comes when we have a <form:options /> tag(or any other tag which takes list as property) on our view(jsp) and the items attribute is referring to a list which is null.

for example:

<form:select path="country" >
     <form:options items="${countryList}" />
</form:select>

in the above case countryList is a simple list containing string objects having country names and to avoid error a not null list should be set in any scope with the name "counrtyList".

It can be set in request scope i.e. can be added to ModelAndView object returned by controller (most common place).
