I have the following p:tabView
:
<p:tabView id="tabView" dynamic="true" cache="false" activeIndex="#{navigationController.activeTabIndex}"
onTabChange="tabChangeCommand([{name:'index', value:index}])">
<p:tab title="#{adbBundle['nav.manageUser']}" id="manageUserTab">
<h:panelGroup layout="block">
<h:form id="manageUserListForm">
<ui:include src="/WEB-INF/includes/userList.xhtml">
<ui:param name="showOnlyActiveUsers" value="#{true}" />
</ui:include>
</h:form>
</h:panelGroup>
</p:tab>
<p:tab title="#{adbBundle['nav.manageRole']}" id="manageRoleTab">
<h:panelGroup layout="block">
<h:form id="manageRoleListForm">
<ui:include src="/WEB-INF/includes/userList.xhtml">
<ui:param name="manageRole" value="manageRole" />
<ui:param name="showOnlyActiveUsers" value="#{false}" />
</ui:include>
</h:form>
</h:panelGroup>
</p:tab>
</p:tabView>
The two tabs both of them have same include, i.e., userList.xhtml
. Inside this userList.xhtml
I have placed a h:outputText
to see the value of ui:param
showOnlyActiveUsers
for testing purpose:
<h:outputText id="showOnlyActiveUsers" value="#{showOnlyActiveUsers}" />
The value of this h:outputText
changes from true
to false
on tab change and vice versa.
The managed bean UserListController
which is in view scope is the back bone for userList.xhtml
. Since it is in view scope it is instantiating once for all these two tabs.
I have a class UserDataModel
which extends LazyDataModel
of Primefaces. An instance of this class is present in UserListController
. I am trying to set a value to a field of UserDataModel
from the getter method of a h:inputHidden
:
<h:inputHidden value="#{userListController.showActiveOnly}" />
which is in userList.xhtml
from UserListController
as:
public String getShowActiveOnly() {
ValueExpression expression = getFacesContext().getApplication().getExpressionFactory().createValueExpression(getFaceletContext(), "#{showOnlyActiveUsers}", Boolean.class);
userDataModel.setShowOnlyActiveUsers(expression.getValue(getFaceletContext());
return "";
}
BUT the value which is generated by expression.getValue(getFaceletContext()
is always false
. I was wondering why the value in the h:outputText
changes from true
to false
, but the value generated by ValueExpression
is always false
?
How can I solve this issue. Any pointer would be very helpful to me.
Edit
protected final FaceletContext getFaceletContext() {
return (FaceletContext) getFacesContext().getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);
}
What I want to achieve is to pass the ui:param
value to the managed bean and from there to the data model.
Edit
userList.xhtml

</p:selectOneRadio>

What I want is to get the current value of that ui:param
from the userList.xhtml
and pass it to the managed bean by some event and set it to the datamodel
. It is also true that the datamodel
is instantiating only once when the managed bean is created as it is in view scope.
