i have a model created by handler calling a declarative service.
a part is generated fom partdescriptor. When the handler has created the model, he passes the model to the part:
broker.send(Topics.AZV_WEBSERVICE, azvDaten);
The part recieves the model:
@Inject @Optional
public void handleEvent(@UIEventTopic(Topics.AZV_WEBSERVICE) AZVDaten incoming)
{
this.azvDaten = incoming;
azvViewer.setInput(this.azvDaten)
}
The model is definatly not null, neither any other injections. Debugged the whole day, without any ideas left. Please help.

Hi Tom,
Thomas Schindl wrote on Wed, 12 March 2014 03:50The input is not be null but one of the elements in the array returned
from your content provider getElements(root) is NULL which is not
allowed in JFace-Viewers!

yes, my ArrayList, which holds the the model values, had 'steps' with null-values.
Took me two days of my life, to find this, but after all, this is solved.
Thanks for your reply and particularly for your awesome javaFX project. Going to migrate to a JavaFX renderer as soon the e4 support for Java 8 is stable
