Only (code)generate propertyChangeSupport field if it does not already exist?

[mediahype]

As soon as a Bean property gets set = "bound" the code generator generates:

private PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(this);

And then I cannot save my Bean to mongo anymore (I use morphia), the error is:

Caused by: org.mongodb.morphia.mapping.MappingException: Error mapping field:java.beans.PropertyChangeSupport.map

I also cannot mark propertyChangeSupport transient, because it gets overwritten by the code generator.

How could this be solved? My (amateur) idea is in the topic.

Sounds like it should be generated as private final transient. And yes, if already present it should not be generated.

Hi Stephen,

I took a look at the codegen code and found it trivial to change the field to private final transient in all cases.

In the end, this would be all I need. My proposal was only for the case that some folks rely on the previous behaviour.

So if you are satisfied with only making it private final transient I can do a pull request.
If you want to implement "Only (code)generate propertyChangeSupport field if it does not already exist" aswell, then I think I would need some words from you how to go about it.

If you could PR the first part, we can keep an RFE open for the second, thanks
