JSF PrimeFaces overlayPanel submit value - jsf

Question

I would like to submit value form jsf page to bean from overlayPanel with checkbox like this:
To show overlay panel and ajax submission I use this code, and see it's OK in debugger:
<p:commandButton id="joinBtn" value="Basic" type="button" disabled="#{dataPropertyCurrent.notJoinable}"/>
<p:overlayPanel id="joinPanel" for="joinBtn" appendToBody="true" dynamic="false">
<f:facet name="header">Details</f:facet>
<p:dataList value="#{treeBean.getDataPropsCouldBeJoinedWith(dataPropertyCurrent)}" type="definition" var="dataJoinVal">
<h:panelGrid columns="2" cellpadding="10">
<h:column>
<p:selectBooleanCheckbox value="#{dataJoinVal.checked}" id="cbID">
<p:ajax event="change" update="cbID" partialSubmit="true"/>
</p:selectBooleanCheckbox>
</h:column>
<h:column>
<h:outputText value="#{dataJoinVal.caption}" />
</h:column>
</h:panelGrid>
</p:dataList>
<!--<p:commandButton value="Apply" id="btnApplyJoin" type="button" process="#parent" />-->
<h:outputLabel value="ID: #{dataPropertyCurrent.joinDataPropertyId}" />
</p:overlayPanel>
But after it when the overlayPanel is hidden and form submit button being pressed with this code:
<p:commandButton value="Apply join" update="joinAccordionPanel,dsAccordionPanelMain" actionListener="#{treeBean.applyJoinOptions}" />
it sets "false" to bean boolean value again.
So how to submit overlayPanel value to bean properly?

I've found explanation here: http://forum.primefaces.org/viewtopic.php?f=3&t=30550#p97737:
"If you are using appendToBody, it's strongly recommended to have a form inside the overlayPanel component that wraps all of the input fields and buttons. This is what you have done in your last solution. However, this means that you cannot place the overlayPanel inside another form in the xhtml page because of the limitation on nesting forms. The best solution is typically to avoid appendToBody wherever it's not absolutely necessary."
Edit
I've added <h:form> inside overlayPanel, and now it works fine:
<p:overlayPanel id="joinPanel" for="joinBtn" appendToBody="true" dynamic="true" >
<h:form id="formTmp">
<f:facet name="header">Details</f:facet>
<p:dataList value="#{treeBean.getDataPropsCouldBeJoinedWith(dataPropertyCurrent)}" type="definition" var="dataJoinVal">
<h:panelGrid columns="2" cellpadding="10">
<h:column>
<p:selectBooleanCheckbox value="#{dataJoinVal.checked}" id="cbID">
<p:ajax event="change" update="cbID" partialSubmit="true"/>
</p:selectBooleanCheckbox>
</h:column>
<h:column>
<h:outputText value="#{dataJoinVal.caption}" />
</h:column>
</h:panelGrid>
</p:dataList>
</h:form>
</p:overlayPanel>
