Java Development Tools

Hi Experts,

We are using jdev 11.1.1.2.
I have created one VO and in that VO for 4 attributes i have created list of values (Combo box with list of values) using some other VOs.
Now I dropped this VO on the page along with create button.

Ran the application
when i click on create button and give the values for the select lists
for the first LOV there is no issues while selecting the values but for the second LOV when a values is selected I am getting null pointer exception as shown below.

<MessageFactory><getMessage>
java.lang.NullPointerException
