if (argument == null) throw illegalargumentexception The argument is not allowed to be null. And I assume it is not null, because the Field onto which PropertyModel<Date>(dummy, "notNullExpression") is attached, isRequired(true).
So null values should not be passed from the wicket framework.. in principle. ** Martin 2009/5/17 Daniele Dellafiore <[email protected]>: > I see that the originating exception is: > > Caused by: java.lang.IllegalArgumentException: Argument "null" must > not be empty or only whitespace. > at com.myapp.dto.Dummy(Dummy.java:76) > > that is, an exception raised by your code. > What is the code at Dummy.java:76? > > On Wed, May 13, 2009 at 7:09 PM, Martin Makundi > <[email protected]> wrote: >>> I think Igor meant for you to post some code. >> >> There's nothing special.. >> >> form = new form >> >> form.add(nestedform = new form) >> >> nestedform.add(new textfield(propertymodel).setRequired(true)); >> >> It works most of the time, but sometimes I get the exception. >> >> ** >> Martin >> >>> >>> cheers, >>> Steve >>> >>> >>> >>> On 13 May 2009, at 17:27, Martin Makundi wrote: >>> >>>> Ok, I was hoping someone has experienced the same stacktrace. >>>> >>>> I will try to reproduce the bug still, maybe I find something. >>>> >>>> ** >>>> Martin >>>> >>>> 2009/5/13 Igor Vaynberg <[email protected]>: >>>>> >>>>> hard to say without having something to play against. >>>>> >>>>> -igor >>>>> >>>>> On Wed, May 13, 2009 at 8:19 AM, Martin Makundi >>>>> <[email protected]> wrote: >>>>>> >>>>>> Hi! >>>>>> >>>>>> I have a data object Dummy whose attribute "value" has a setMethod >>>>>> (setValue) that does not allow the given value to be an empty string >>>>>> or null. >>>>>> >>>>>> This model object is attached to a property model new >>>>>> PropertyModel(dummy, "value") and the propertymodel is passed to a >>>>>> TextField component whose "setRequired=true".. >>>>>> >>>>>> Normally, when I access the page, the form works perfectly.
