Hi Tim,
Thanks for the welcome and the reply I appreciate it (and sorry for the bulk of information, I figured better to much then to little).
My controller impression came from this
tutorial and makes sense to me, however this would not be the place to discuss this.
I am a bit confused regarding your remark, I am familiar with HTML and how it functions (a lot of .NET experience). I am not really looking for a AJAX solution, I was in the impression that it would be possible to do a postback to the server by using the onchange="this.form.submit()" javascript, and be able to call the 'valueChanged' method (as described in this article
https://www.ibm.com/developerworks/library/j-jsf2/, where a similar solution is done). And basically that is the same I do with the 'open' note link which does a postback and fires the "editDoc" method in the EindOpdrachtContr class.
So what I basically want is for the selectOneMenu to make a roundtrip to the server when the users changes its value and the response should contain the updated Note textarea.
Thanks Maurits
