------------------------------------
There is workaround: reset JSF components values manually. Use
resetUIComponentValueRecursively( String componentId ) where componentId is form id.

Key: RF-7136
URL: https://jira.jboss.org/jira/browse/RF-7136
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.0
Environment: RichFaces 3.3.0GA
Mojarra JSF Implementation 1.2_12-b01-FCS
Reporter: Denis Petrunin
Assignee: Tsikhon Kuprevich
1) open edit.jsf page (see below)
2) input "1" into "Id" field, click "Edit" button
3) make a note that "Name" field contains "First", "Note"
field contains "Note-1"
4) clear "Name" field, click "Save" button
5) make a not that the error message is shown: "fmEdit:itName: Validation Error:
Value is required."
6) input "2" into "Id" field, click "Edit" button
7) make a note that "Name" field contains "Second", "Note"
field still contains "Note-1"
Expected result: "Note" field must contain "Note-2"
I think other UIInput, UIData are affected as well.
