<af:inputListOfValues label="Branch Name"
popupTitle="Search and Result Dialog"
id="ilov1"
model="#{pageFlowScope.organizationLOV.param['bindings.Organization'].listOfValuesModel}"
converter="#{pageFlowScope.organizationLOV.param['bindings.Organization'].convert['latinDesc']}"
valueChangeListener="#{viewScope.salaryBenefitsReportForm.branchChange}"
binding="#{viewScope.salaryBenefitsReportForm.branchName}"
rendered="true" visible="false"/>
<af:inputListOfValues label="Department Name"
popupTitle="Search and Result Dialog"
id="ilov2"
model="#{pageFlowScope.objectLOV.param['bindings.Department'].listOfValuesModel}"
converter="#{pageFlowScope.objectLOV.param['bindings.Department'].convert['latinDesc']}"
valueChangeListener="#{viewScope.salaryBenefitsReportForm.departmentChange}"
binding="#{viewScope.salaryBenefitsReportForm.departmentName}"
rendered="true" visible="false"/>
this is code in jsff .
and class code are following
public void reportBy(ValueChangeEvent valueChangeEvent) {
String value=(String)valueChangeEvent.getNewValue();
System.out.println(value);
if(value.equals("Branch")){
branchName.setVisible(true);
departmentName.setVisible(false);
AdfFacesContext.getCurrentInstance().addPartialTarget(branchName);
AdfFacesContext.getCurrentInstance().addPartialTarget(departmentName);
if(value.equals("Department")){
departmentName.setVisible(true);
branchName.setVisible(false);
AdfFacesContext.getCurrentInstance().addPartialTarget(departmentName);
AdfFacesContext.getCurrentInstance().addPartialTarget(branchName);
}
