I created a service to create beanmodels like this:
public class BeanModelHelperImpl implements BeanModelHelper
{
/**
* Create a BeanModel for a class from an ordered array of
* Strings for the fieldnames.
*
* @param clazz the class for which the model is to be built
* @param fields the Fieldnames
* @return the created BeanModel
*/
public BeanModel createBeanModel(Class clazz, String[] fields,
BeanModelSource beanModelSource,
ComponentResources componentResources)
{
HashSet<String> fieldNames = new HashSet<String>();
for (String s : fields)
{
fieldNames.add(s.toLowerCase());
}
BeanModel beanModel = beanModelSource.create(clazz, false,
componentResources);
List<String> actualProperties = beanModel.getPropertyNames();
for (String s : actualProperties)
{
if (!fieldNames.contains(s.toLowerCase()))
beanModel.remove(s);
}
beanModel.reorder(fields);
return beanModel;
}
}
If I call this with a line like
Beanmodel model = beanModelHelper.createBeanModel(Master.class, new
String[]{"name","slave.name","slave.enslaved", source, resources);
an exception is thrown:
Bean editor model for entities.Master does not contain a property named
'slave'. Available properties: name.
This is to be expected since the beanModel created by the beanModelSource
contains only the primitive (and Date) properties of any given class it
seems, so when I have a property which itself is a class with primitive
properties as in the example there seems to be no easy way get these into a
BeanModel save by creating a new class with the needed properties as a kind
of transferobject.
