<h:selectOneListbox with dynamic values submit error

[Dan MacLeod]

I have a <h:selectOneListbox that is populated with SelectItems stored in a session variable array. A user can also add or remove values to the list from the JSP.

If the values never change, everything works fine. The problem is when a user adds or removes values from the listBox and submits the form I get errors.
(ERROR example " "msqPseudoCityListBox": " Conversion Error setting value 'TEST1' for 'null Converter'. )

Any ideas on what is causing this?

thanks

<h:selectOneListbox styleClass="selectOneListbox" id="msqPseudoCityListBox" value="#{pc_ActionQueueContent.sessionContainer.testing}"
style="width: 90px" size="2" valueChangeListener="#{pc_ActionQueueContent.handleMsqPseudoCityListBoxValueChange}" onchange="return func_1(this, event);">
<f:selectItems value="#{pc_ActionQueueContent.sessionContainer.msqList}" />
</h:selectOneListbox>

I was able to implement a dynamic combo with the help of this blog.
JSF SelectBox

Hope this will help you. The key here is that your managed bean should be in session scope. Other ways to implement this is also discussed in this blog
