form value within ajax rendered panel not appearing

[oidsman]

Hi,

I have a <form> tag on a page and part of the code within that page is as below:-

Code: Select all

<p:outputPanel id="bandedStep">
			
			<p:panel header="#{pageText.page_purchase_header_step_banded_2}" rendered="#{purchaseBean.rateDisplay and tempSchemeUnit.policy.bandedPremium}">
			
					<h:outputText value="#{pageText.page_purchase_band_question_text}" />
					<p:spacer width="8" height="10" />
					<h:panelGroup>
						<h:selectOneMenu styleClass="selectOneMenu" id="titlesSelect1"
							value="#{purchaseBean.testBand}">
							<f:selectItems value="#{purchaseBean.bands}" />
						</h:selectOneMenu>
					</h:panelGroup>
					<p:spacer width="8" height="10" />
					<p:commandButton rendered="#{tempSchemeUnit.policy.bandedPremium}"
						value="#{pageText.page_purchase_button_retrieve_premium}"
						action="#{purchaseBean.doChooseBand}" update="out bandedStep">

					</p:commandButton>
			</p:panel>
			</p:outputPanel>
	

The ouputpanel bandedStep is updated further up the page and appears as part of the process. The problem is that the <h:selectOneMenu> value (purchaseBean.testBand) is not updated if the rendered tag (rendered="#{purchaseBean.rateDisplay and tempSchemeUnit.policy.bandedPremium}") is in the code. If I remove that rendered part , the value is submitted to the backing bean.

Can anyone explain why this is happening?
