JSF : dynamically loaded page commandButton not working - ajax

Question

I have a page that contains a PrimeFaces accordion panel, in each panel is a PrimeFaces datatable. Below the datatable is a button "Add study" for example and when this button is click I want to dynamically load a page into a <h:panelGroup> using a <ui:include>. When the button is being click I want to dynamically change the src value from the <ui:include> so that my page is loaded in the <h:panelGroup>. Now the problem is the following:
My managed bean is set to #RequestScoped and when I click on my button nothing is being rendered.
If I set my managed bean to #SessionScoped the <h:panelGroup> is filled after the second click on the button, the first click doesn't do anything.
Used technologies : JSF2.0, PrimeFaces, Facelets
Here are some code snippets :
Main Page
<h:panelGroup id="content" layout="block">
<ui:include src="#{studyBean.includePage}"/>
</h:panelGroup>
<div id="dashboard">
<h:form id="form" prependId="false">
<h:outputText value="Welkom #{loginBean.username}"/>
<p:accordionPanel autoHeight="true" effect="bounceslide">
<p:tab title="My studies">
<p:dataTable var="study" value="#{studyBean.studiesByUser}" id="studyTable"
emptyMessage="No studies found for given user" paginator="true" rows="10"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="5,10,15" rowSelectListener="#{studyBean.onRowSelect}"
selectionMode="single">
<p:column headerText="StartDate" sortBy="#{study.startDate}"
filterBy="#{study.startDate}"
filterMatchMode="contains" style="width: 100px;">
<h:outputText value="#{study.startDate}">
<f:convertDateTime pattern="dd/MM/yyyy" type="date" timeZone="CET"/>
</h:outputText>
</p:column>
<p:column headerText="EndDate" sortBy="#{study.endDate}"
filterBy="#{study.endDate}}"
filterMatchMode="contains" style="width: 100px;">
<h:outputText value="#{study.endDate}">
<f:convertDateTime pattern="dd/MM/yyyy" type="date" timeZone="CET"/>
</h:outputText>
</p:column>
<p:column headerText="School" sortBy="#{study.school}" filterBy="#{study.school}}"
filterMatchMode="contains" style="width: 100px;">
<h:outputText value="#{study.school}"/>
</p:column>
<p:column headerText="Specialization" sortBy="#{study.specialization}"
filterBy="#{study.specialization}}" filterMatchMode="contains"
style="width: 100px;">
<h:outputText value="#{study.specialization}"/>
</p:column>
<p:column headerText="Remarks" sortBy="#{study.remarks}"
filterBy="#{study.remarks}}"
filterMatchMode="contains" style="width: 100px;">
<h:outputText value="#{study.remarks}"/>
</p:column>
</p:dataTable>
<h:commandButton id="btnAddStudy" title="Add Study" value="Add Study">
<f:ajax render=":content" execute="form" listener="# {studyBean.navigate}"/>
<f:param name="action" value="add"/>
</h:commandButton>
</p:tab>
</p:accordionPanel>
</h:form>
So as you can see is my <h:panelGroup> outside my form.
This is the included page (as example)
<h:body>
<ui:composition template="../template/template.xhtml">
<ui:define name="body">
<f:view contentType="text/html">
<ui:composition>
<h:form id="studyForm" prependId="false">
<p:messages />
<h:message for="startDate"/>
<h:message for="endDate"/>
<h:message for="school"/>
<h:message for="diploma1"/>
<h:message for="diploma2"/>
<h:message for="diploma3"/>
<h:message for="specialization1"/>
<h:message for="specialization2"/>
<h:message for="specialization3"/>
<h:message for="remarks1"/>
<h:message for="remarks2"/>
<h:message for="remarks3"/>
<h:outputText class="label" value="Start date: "/>
<h:inputText id="startDate" styleClass="inputtext validate[required,custom[date]]"
value="#{studyBean.startDate}">
<f:convertDateTime pattern="dd/MM/yyyy" timeZone="CET"/>
</h:inputText>
<h:outputText class="label" value="End date: "/>
<h:inputText id="endDate" styleClass="inputtext validate[required,custom[date]]"
value="#{studyBean.endDate}">
<f:convertDateTime pattern="dd/MM/yyyy" timeZone="CET"/>
</h:inputText>
<h:outputText class="label" value="school: "/>

<h:inputText id="specialization3" styleClass="inputtext validate[maxSize[50]]"

<h:outputText class="label" value="Diploma: "/>
<h:inputText id="diploma1" styleClass="inputtext validate[maxSize[50]]"
value="#{studyBean.diploma[0]}"/>
<h:inputText id="diploma2" styleClass="inputtext validate[maxSize[50]]"
value="#{studyBean.diploma[1]}"/>
<h:inputText id="diploma3" styleClass="inputtext validate[maxSize[50]]"

<h:inputText id="remarks3" styleClass="inputtext validate[maxSize[200]]"
value="#{studyBean.remarks[2]}"/>
<h:commandButton action="cancel" value="cancel" immediate="true"/>
<p:commandButton id="btnAddStudyDetail" value="add study" actionListener="#{studyBean.addStudy}"
update="studyTable" oncomplete="clearAddStudy()"/>
</h:form>
</ui:composition>
</f:view>
</ui:define>
</ui:composition>
</h:body>
Managed Bean #RequestScoped
#ManagedBean
#RequestScoped
public class StudyBean {
public String navigate() {
FacesContext facesContext = FacesContext.getCurrentInstance();
try {
action = (((HttpServletRequest) facesContext.getExternalContext().getRequest()).getParameter("action"));
if (action.equals("add")) {
//vull de velden
includePage = "studyDetail.xhtml";
}
facesContext = FacesContext.getCurrentInstance();
UIViewRoot root = facesContext.getViewRoot();
UIComponent form = root.findComponent("form");
dataTable = form.findComponent("studyTable");
System.out.println(dataTable);
System.out.println(root);
} catch (Exception e) {
facesContext.addMessage("form", new FacesMessage("You must select a study."));
}
return null;
}
}
Thanks in advance.
UPDATE
Now I am able to dynamically load the page in my <ui:include> but I have another problem now, when the page is loaded and I want to click on my button in the loaded page the action to which it is bound doesn't execute. So I don't get into my backing bean, I already tried to put the scope of my bean to #ViewScoped but no success.
Please help me as I am getting desperate.
