[jira] [Created] (TRINIDAD-2134) NullPointerException in StateManagerImpl._calculateTokenStateSaving

NullPointerException in StateManagerImpl._calculateTokenStateSaving
-------------------------------------------------------------------

                 Key: TRINIDAD-2134
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-2134
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Gabrielle Crawford
            Assignee: Gabrielle Crawford


In the fix for this issue
https://issues.apache.org/jira/browse/TRINIDAD-2017

This line of code was added to StateManagerImpl._calculateTokenStateSaving
           UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();

However in certain situations we are calling StateManagerImpl.isValidViewStateToken() (which calls StateManagerImpl._calculateTokenStateSaving) from a servlet filter, which mean the FacesContext is null. Note that both these methods take the externalContext, and not the FacesContext, as params.
