No Interpreter set in FOM_Cocoon

[Michel Erard <mi...@corix.ch>]

Hello, 
 
I'm using cocoon 2.2 and the suggestion list widget. For the ajax combo I turned off the autocompletion.
 
Now sometimes I have a NullPointerException in the class FOM_Cocoon in Method:
 
public void forwardTo(...)
 
in line 718 the method getInterpreter() returns null.
 
But not all the times :-(
 
When I turn on autoCompletion on the field is no Problem. But then the listeners linked with the field aren't properly called. So I tried without the completion.
 
Does anyone already have this Problem or knows a Solution?
 
Thanks Mike
