The goal of Seam components refactoring is to make system-wide code changes without affecting the behavior of the program. Seam Tools provides assistance with code refactoring.
Seam refactoring tools includes the following refactoring operations:
Refactoring commands are available from the context menus of several views and editors; for details, see Section 11.1, “Using the Refactorinig Wizard”.

The view represents two windows: one with the original source code and the other with refactored one.
With the help of

buttons you can quickly navigate between the differences in the code. If you don't agree with some changes you can't undo them but you can remove the class from the list of classes that need refactoring.
To apply the changes click Finish.
Renaming the selected seam component corrects all references to the component (also in other files in the project). Renaming a type doesn't allow to rename similarly named variables and methods.
Renaming a Seam component could be performed in the:
If you want to rename certain seam component using Java editor, first of all it's necessary to open it. If you don't know, where the seam component is declared, use Section 5.2.2, “Open Seam Component” icon.
