First, JFace and Data binding questions belong in the eclipse.platform
newsgroups, since they are both at a layer above SWT. I've copied
eclipse.platform to this reply.
Second, you'll have to be more specific; refactor operations are
general-purpose and I don't know what kinds of data-binding-specific
things you might be thinking of.

Kerem,
Are you talking about changing property name strings when you rename
your bean properties? If that's what you're asking, then no, Eclipse
can not help you much. I've found that by exposing the property name
string as a public static field on the bean class, that refactoring
becomes a little nicer:
public class Person {
public static final String NAME = "name";
private String name;
public String getName() { return name; }
public void setName(String name) {
firePropertyChange(NAME, this.name, this.name = name);
}
}
Then, in binding code, you want to use the static field instead of a
literal string for the property name:
bindingContext.bindValue(
SWTObservables.observeText(nameText),
BeansObservables.observeValue(person, Person.NAME),
null,
null);
Thus if you decide in the future to change the "name" property to
"lastName" then the change is simpler:
* Rename name field to lastName
* Rename getName() method to getLastName()
* Rename setName() method to setLastName()
* Rename NAME field to LAST_NAME
* Change the value of LAST_NAME from "name" to "lastName"
Hope this helps,
Matthew

Yes I know Eclipse cannot do it, I thought I could find a plugin to bring
this feature to eclipse.
Thanks for you hint.
