Convert Date on SelectManyCheckbox Selection - jsf

Question

i have a simple problem but i didnot find a solution for it.
I have a simple p:selectCheckboxMenu and i want use the selectedDates after click on the button.
I tried it with f:convertDateTime
<h:form id="mainform">
<p:panelGrid columns="2">
<p:selectCheckboxMenu label="Date" value="#{myBean.selectedDates}">
<f:selectItems value="#{myBean.dates}" var="date" itemValue="#{date}" itemLabel="#{myBean.convertDate(date)}"/>
<f:convertDateTime type="date" pattern="dd-MM-yyyy"/>
</p:selectCheckboxMenu>
<p:commandButton value="Test" actionListener="#{myBean.printDates}"/>
</p:panelGrid>
but than i get an Error- Message: "Invaild Value".
Than i tried a Converter:
#FacesConverter("myDateConverter")
public class MyDateConverter extends DateTimeConverter{
public MyDateConverter(){
setPattern("MM/dd/yyyy");
}}
and
<p:selectCheckboxMenu label="Date" value="#{myBean.selectedDates}" converter="myDateConverter">
But same error message. When i use no converter i get "String"- Values in my Date-List because type erasure.
Question: How i get the selected dates as dates?
Here is my bean for completeness:
#ManagedBean(name = "myBean")
#ViewScoped
public class MyBean implements Serializable {
private List<Date> dates;
private List<Date> selectedDates;
private SimpleDateFormat dateFormat;
#PostConstruct
public void init() {
System.out.println("POST CONSTRUCT!");
dateFormat = new SimpleDateFormat("yyyy.MM.dd");
dates = new ArrayList<Date>();
dates.add(new Date());
}
/**
*
*/
public void printDates(){
for(Date d : selectedDates){
System.out.println(d);
}
}
/**
*
* #param date
* #return
*/
public String convertDate(Date date){
return dateFormat.format(date);
}

The converter is the source of the problem as it removes the time and then it uses the default time when converting back to Date.
You can use
< f:convertDateTime pattern="yyyy-MM-dd HH:mm:ss.SSS Z" />
or try with a < f:datetimeconverter >
