That's strange. Your PropertyConduit implementation and use looks correct
to me. Could you post the full stack trace please? The datatype is defined
by the DataTypeAnalyzer service, and its configuration provided by
Tapestry alread maps BigDecimal to the "number" datatype.

The resulting model contains properties with a null datatype.
That surely looks like something you shouldn't do. How can the component
know how edit an value which hasn't a data type? In this case, you
either
define a custom datatype and provide edition and viewing blocks for them
or you don't add this property to the bean model.
It's a simple number. Okay, not simple, but BigDecimal.
However, I did not set/change the datatype myself, as you can see in the
posted code.
If you need more information like how I build the PropertyConduit,
please let me know.
Please post it.
private void addPropertyConduitsToBeanModel(BeanModel<TreatmentModel>
model) {
for (final ValueType valueTypes : dao.getValueTypes()) {
PropertyConduit propertyConduit = new PropertyConduit() {
public Object get(Object instance) {
MyObject myObject = (MyObject) instance;
return model.getValue(valueType);
}
public void set(Object instance, Object value) {
MyObject myObject = (MyObject) instance;
BigDecimal myValue = (BigDecimal) value;
myObject.setValue(valueType, value);
}
public Class getPropertyType() {
return BigDecimal.class;
}
public <T extends Annotation> T getAnnotation(Class<T>
annotationClass) {
return null;
}
};
String propertyName = valueType.getName();
model.add(propertyName, propertyConduit);
}
}
