"javax.el.ELException: Property not found on type" on a method expression

Question

I am using Primefaces 5.2, jsf 2.2 and Tomcat 8 on a Linux server. This is the line in my xhtml:

<p:fileUpload fileUploadListener="#{uploadController.complete}" multiple="true"/>

The method in the class UploadController:

 public void complete(FileUploadEvent fileUploadEvent) {
     UploadedFile item = fileUploadEvent.getFile();
     // ... etc. nothing special, all standard reading
 }

If I start up my page in a jetty, everything works fine.

But if I start it up on the linux server with tomcat 8, i got

javax.el.ELException Property 'complete' not found on type

exception. I also tried to run my code on my Windows machine in a tomcat 8 (started up by Maven in a cargo container). No problem there.

One step further was to put a parameter for method UploadController.complete :

    <p:fileUpload fileUploadListener="#{uploadController.complete(fileUploadEvent)}" multiple="true"/>

...the only way a parameter was excepted (no f:param , f:attribute,... were accepted => same ELException). But then the event "fileUploadEvent" in UploadController is NULL.

How to solve the problem?
