---------------------------------

             Summary: NullPointerException when PrimeFaces FileUpload used in composite component
                 Key: MYFACES-4590
                 URL: https://issues.apache.org/jira/browse/MYFACES-4590
             Project: MyFaces Core
          Issue Type: Bug
          Components: General
    Affects Versions: 4.0.0, 4.0.1
         Environment: primefaces-test project, jakarta branch 
            Reporter: Manuel K


Using the following composite component, an exception occurs upon rendering only on MyFaces but not on Mojarra. Please let me know if this is a PrimeFaces bug instead and I'll open an issue there.

The exception:

Caused by: java.lang.NullPointerException: Cannot invoke "java.lang.Long.longValue()" because the return value of "org.primefaces.component.fileupload.FileUpload.getSizeLimit()" is null
