             Summary: Conversion error for select items of type String
                 Key: MYFACES-4645
                 URL: https://issues.apache.org/jira/browse/MYFACES-4645
             Project: MyFaces Core
          Issue Type: Bug
          Components: General
    Affects Versions: 4.0.1
            Reporter: Manuel K

An error occurs when using select items of type String in combination with the 
OmniFaces SelectItemsIndexConverter. MyFaces seems to attempt to convert the 
submitted value twice, which leads to a NumberFormatException on the second try.

I suspect the following if-statement to be the culprit, but of course have no 
idea why it is needed in other cases or how to fix the problem:

Please see the attached reproducer, which produces the error when selecting a 
value in the SelectOneMenu when run with 
{noformat}
mvn clean jetty:run -Pmyfaces40{noformat}
