Manuel K created MYFACES-4590:
---------------------------------
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.
{code:java}

</ui:component> {code}
The exception:
{code:java}
Caused by: java.lang.NullPointerException: Cannot invoke
"java.lang.Long.longValue()" because the return value of
"org.primefaces.component.fileupload.FileUpload.getSizeLimit()" is null
