HtmlResponseStateManager.getSavedState() should handle javax.faces.ViewState=""
-------------------------------------------------------------------------------
Key: MYFACES-1975
URL: https://issues.apache.org/jira/browse/MYFACES-1975
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 1.2.3
Environment: Any
Reporter: Curtiss Howard
Priority: Minor
HtmlResponseStateManager.getSavedState() does not seem to handle the request
attribute "javax.faces.ViewState" being an empty string. That is to say, when
the request attribute does not exist, a new state is created, but otherwise an
attempt is made to reconstruct the view state. In the case that the attribute
is an empty string, you'll get an exception similar to the following:
javax.faces.FacesException: java.io.EOFException
at
org.apache.myfaces.shared_impl.util.StateUtils.getAsObject(StateUtils.java:350)
at
org.apache.myfaces.shared_impl.util.StateUtils.reconstruct(StateUtils.java:246)
at
org.apache.myfaces.renderkit.html.HtmlResponseStateManager.getSavedState(HtmlResponseStateManager.java:188)
at
org.apache.myfaces.renderkit.html.HtmlResponseStateManager.getTreeStructureToRestore(HtmlResponseStateManager.java:149)
This does not occur on the Sun RI implementation (i.e., it returns a new state
in this case), and I think due to this being an issue that should be handled
(and a trivial change to boot) that it should be fixed.
