Dataobject scope and howto set property in javabean - n00b question?

Question

1. I try to use my JavaBean in uix page as DataObject ( with generated adapter ).
It works fine for geter methods to render properties but hot to set properties ( call setters )?
2. That JavaBean calls long select method in BMP entity bean and I wonder what is a "scope" ( as it is in jsp:useBean ) of my DataObject wrapped JavaBean.

1. I try to use my JavaBean in uix page as DataObject ( with generated adapter ).
It works fine for geter methods to render properties but hot to set properties ( call setters )?You'll need to use Java code in an event handler. Or, you can use
the built-in UIX-Struts integration support, and let Struts automatically
set the JavaBean properties.
JDev 9.0.4 will include a <set> EventHandler that will provide declarative support for
setting properties of JavaBeans, e.g., grabbing a property from the request and setting
it on a JavaBean from entirely within UIX.
2. That JavaBean calls long select method in BMP entity bean and I wonder what is a
"scope" ( as it is in jsp:useBean ) of my DataObject wrapped JavaBean.If the DataObject is created during rendering, its lifetime is a single request.
However, a DataObject wrapper that only lives for a single request can easily
wrap a JavaBean that lives for multiple requests.
I wouldn't worry about caching the DataObject wrappers - they're very lightweight.
But if your JavaBean is expensive to create, then by all means cache that JavaBean.
