Re: select problem render queue
I tried to see what was in my selectmodel after the factory loading with
this code :
// initialize selectmodels
selectType = selectModelFactory.create(typeClientList, nomType);
ListOptionModel optionModelList = selectType.getOptions();
System.out.println(begin);
for (OptionModel optionModel : optionModelList) {
System.out.println(optionModel.getLabel());
System.out.println(optionModel.getValue());
}
System.out.println(end);
And in the console I see that I have exactly what I want and I don't see
any Null in my selectmodel.
@Bob : How do you resolved your problem ?
Anyone alse to help me on this ? I'm stuck on thsi problem :(

I haven't read through this thread very carefully, but last week I got
a nearly identical stack trace. It was from Palette, not Select, but
those components have a lot of identical code. In my case the problem
was that the SelectModel had all of the expected values *except* the
selected value. Tapestry didn't do a good job with the error messages
in that case.

Re: select problem render queue
If I read Bob right, I think Bob said his problem was not due to nulls, it was
due to the selected value not being one of the values in the OptionModel.
It might also be worth trying secure=literal:false on the Select.

Re: select problem render queue
the null pointer exception comes from :
at org.apache.tapestry5.internal.util.SelectModelRenderer.
option(SelectModelRenderer.java:51)
which is, in the code of tapestry this :
@SuppressWarnings(unchecked)
public void option(OptionModel optionModel)
{
Object optionValue = optionModel.getValue();
* String clientValue = encoder.toClient(optionValue); --- line 51*
writer.element(option, value, clientValue);
if (isOptionSelected(optionModel, clientValue))
writer.attributes(selected, selected);
writeDisabled(optionModel.isDisabled());
writeAttributes(optionModel.getAttributes());
writer.write(optionModel.getLabel());
writer.end();
}
So in this line it should execute the toClient method of my ValueEncoder so
I added some system.out.println in it just to see if it really does it :
public class TypeClientDtoEncoder implements ValueEncoderTypeClientDto,
ValueEncoderFactoryTypeClientDto {
@Inject
private IServiceTypeClient serviceTypeClient;
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toClient(java.lang.Object)
*/
@Override
public String toClient(TypeClientDto value) {
// return the given object's ID
*System.out.println(abcdef);*
* System.out.println(encoder typeclient toclient);*
return String.valueOf(value.getId());
}
/*
* (non-Javadoc)
*
* @see org.apache.tapestry5.ValueEncoder#toValue(java.lang.String)
*/
@Override
public TypeClientDto toValue(String clientValue) {
// find the typeclientdto object of the given ID in the database
System.out.println(abcdef);
System.out.println(encoder typeclient tovalue);
return serviceTypeClient.findTypeClientDto(Long.parseLong(clientValue));
}
// let this ValueEncoder also serve as a ValueEncoderFactory
/*
* (non-Javadoc)
*
* @see
* org.apache.tapestry5.services.ValueEncoderFactory#create(java.lang.Class)
*/
@Override
public ValueEncoderTypeClientDto create(ClassTypeClientDto type) {
return this;
}
}
But nothing appears in the console, so the problem is here, why it doesn't
pass in the method toClient of my ValueEncoder ?

Have you checked whether you're passing a null value to the Select's
encoder parameter?

Why is it strange? @Property just creates getter and setter. It doesn't
set field values. You were probably only setting the field in
setupRender(), which isn't called when a form submission is done. For
that, you could have used onPrepare() (triggered by Form) instead, as it's
called before the form is rendered and before the form submission is
processed.
