Hi Johannes

Make sure you are editing the base CDF and not the effective
CDF. There's a cyclic field to change the CDF type in the CDF edit
form. If you are trying to change the CDF for a device that you don't
have write access to, you can add this to your .cdsinit. However, keep
in mind that you have to run this code every time you do refresh from
disk. 

(setq myCDF (cdfGetBaseCellCDF (ddGetObj "libName" "cellName")))
(mapc
  (lambda (myCDFParam)
    (cond
        ((equal (getq myCDFParam name) "resType")
         (putpropq myCDFParam "RPHR" defValue)
         (putpropq myCDFParam "RPHR" value))
        ((equal (getq myCDFparam name) "model")
         (putpropq myCDFParam "RPHR" defValue))))
    (getq myCDF parameters))
