OpenFaces simple Ajax problem

[Tom Fulton]

Hello everyone,

I have worked with RichFaces and some other component libraries a bit less extensively (such as PrimeFaces) and am trying to get a fairly simple OpenFaces app to work. I am hoping someone can help.

I have a page that displays accounts in a selectOneListbox. Using vanilla JSF, I have the form being submitted when the user selects a different account, which re-displays the current page and shows the balance for the newly-selected account. This works fine, except that I don't want to have to submit the form. Hence: Ajax.

Here is a simplified portion of my form:

		<td><h:selectOneListbox id="account"
								value="#{accountBacking.selectedAccountID}" size="4">
								<f:selectItems value="#{accountBacking.accountSelectList}" />
								<o:ajax render="withdrawBalance account" listener="#{accountBacking.changeAccount}" />
							</h:selectOneListbox></td>
							<td>
								<h:outputText id="withdrawBalance" required="true" value="#{accountBacking.selectedAccountBalance}" size="20" maxlength="30" >
									<f:convertNumber type="currency" 					
										maxFractionDigits="2" currencySymbol="$"/>
								</h:outputText>
							</td>

Whenever I run this, I get an IllegalStateException pointing at the selectOneListbox. I am assuming that this is caused by attempting to restore the state of this component, but for the life of me I can't see what I'm doing wrong. I've tried a number of different approaches from the OpenFaces Developer's Guide, but nothing seems to work. Any ideas?

Thanks in advance.
