Testcase:

1. Create seam war project
2. Create seam action with "first" as component name
3. Add next string to components.xml:

<component class="org.domain.<projectname>.session.First" name="first2" />

4. Open First.java file
5. Select Seam->Rename Seam Component menu

ASSERT: Refactoring wizard appears initialized with component "first".

FAIL: Refactoring wizard appears initialized with component "first2".

Note: Issue may be not reproduced with names "first" and "first2" because Seam model returns components based on class First in java.util.Set, so that there is indeterminacy which component will be selected. Then other names may be tried, or more components in xml declared.
