Re: [Javapathfinder-user] Array of Double Question

[Peter C. M. <pcm...@em...>]

Outch! Index screwup in ElementInfo.get/setLongElement(), no idea how  
this sneaked in. The index values in Fields are int[] based, so the  
ElementInfo methods have to be adjusted *2:

   public void setLongElement(int index, long value) {
     checkArray(index);
     cloneFields().setLongValue(index*2, value);
   }

   public long getLongElement(int index) {
     checkArray(index);
     return fields.getLongValue(index*2);
   }

It's committed, but as always it takes a while until this shows up in  
the public CVS
