Problem with calendar

[glister]

Hey,

in my JSF Page i have a calendar component included :

Code: Select all

      <div class="element">
                        <p:calendar value="#{createOrder.orderDate}" id="szDate" mode="popup" locale="de" startWeekday="1" pattern="dd.MM.yyyy" required="true" requiredMessage="Datum wird benötigt" />
                        <h:message for="szDate" styleClass="error" />
       </div>

createOrder.orderDate is defined as a String in my backing bean.

There is a separate input Element in my form to get a currency.

Code: Select all

                    <div class="element">
                        <h:inputText required="true" id="dblKosten" size="20" maxlength="40" value="#{createOrder.dblGesamtkosten}" >
                        </h:inputText>
                        <h:message for="dblKosten"></h:message>
                     </div>

In my Backing Bean i validate and convert the currency to BigDecimal. if the validate Method returns null, a FacesMessage returns.


So now to my problem. If i type 126, in my currency input and submit, i get the following error:

Code: Select all

if i type 126,00 ... no error like above occurs.

any idea ???

// EDIT

i traced through the DateFormat.java source to find the error :

He calls the format() Method where

obj = (String) "Mon Feb 08 00:00:00 CET 2010"

Code: Select all

    public final StringBuffer format(Object obj, StringBuffer toAppendTo,
                                     FieldPosition fieldPosition)
    {
        if (obj instanceof Date)
            return format( (Date)obj, toAppendTo, fieldPosition );
        else if (obj instanceof Number)
            return format( new Date(((Number)obj).longValue()),
                          toAppendTo, fieldPosition );
        else 
            throw new IllegalArgumentException("Cannot format given Object as a Date");
    }

I hope its helps ...

Hi,

Why createOrder.orderDate is a String? Calendar works with java.util.Date type values.

Hey cagatay.civici,

don't know why .... but i thought input components works with Strings, thank you.

my shame
