选中“全部检查”复选框不会调用p：ajax标签JSF

Question

ajax doesn't work when I check 'check all box' checkbox.

 <p:selectCheckboxMenu id="departmantCheckBox" value="#{marketAnalysisReportController.selectedDepartmants}"  filter="true" filterMatchMode="startsWith" panelStyle="width:250px">
            <p:ajax update="saleCheckBox" listener="#{marketAnalysisReportController.updateSales}"/>
            <f:selectItems value="#{marketAnalysisReportController.departmants}" var="departmant"
                            itemValue="#{departmant}"
                            itemLabel="#{departmant.name}"/>
        </p:selectCheckboxMenu>

Here's update method

public void updateSales(){
        sales=new ArrayList<Obje>();
        System.out.println("updatesales");
        for(Obje departmant: selectedDepartmants){
            System.out.println(departmant.name);
            if(departmant.getName().equals("test1")){
                sales.add(new Obje(20,"salestest20"));
                sales.add(new Obje(21,"salestest21"));
                System.out.println("add");
            }
            if(departmant.getName().equals("test2")){
                sales.add(new Obje(200,"salestest200"));
                sales.add(new Obje(210,"salestest210"));
            }
            if(departmant.getName().equals("test3")){
                sales.add(new Obje(250,"salestest250"));
                sales.add(new Obje(260,"salestest260"));
            }
            if(departmant==null || departmant.equals("")){
                sales=new ArrayList<Obje>();
            }
        }
    }

If I check boxes one by one, it works, but when I check 'check all checkboxes' it doesn't update sales. I can share more detail if you need.

As Kukeltje allready pointed out the 'select all'- action does not fire the default ajax event which is caught by your tag. The ajax event that is being fired when you select all is called 'toggleSelect', so you need to add another ajax tag like this:

< p:ajax event="toggleSelect"...
