[Enhancement] Make setBeanProperties to not depend on it field type.

The field dependency for the bean property way is great to allow **making the bean transient (it isn't currently working, and I wonder if it is intended to)** but with this it is impossible to make some tricks as set a String and then, in the getter/setter make wathever magic to de/serialize de field type. ie:

```
!thing
template: "t1"
```

and after in code:

```
TemplateType template;

String getTemplate() {
return template.getName();
}

void setTemplate(String template) {
this.template = getTemplateForName(template);
}
```
