Absence of pictures with RA'AD on JF-17 can trigger this debate. However I don't think it is that much a problem. It may be just that PAF is not focusing at this now. They already have Mirage for this so no rush. PAF seems more concerned with Air to Air combat capability than anything else.
However a fair case can be made that Ra,ad will integrate successfully. Weight as per Wiki is 1100 kg. That's around 2400 pounds. There have been rumours that JFT can't carry a 1000 kg class weapon on its wing stations. Pictures of 2000 lbs bombs only appeared on fuselage station thus giving rise to this speculation. It might just be true for Blk-1 standard. However if you have seen recently released video of Blk-2, it is carrying two 2000 lbs bombs on wings. So station can carry this weight. CM-400 AKG also weighs 900-950 kg and has been seen on wings of JFT. So I don't think there is problem. It's just matter of priorities perhaps. PAF sees other things more important.
