Hi guys.  Has anyone else had a problem with DIVA components 
disappearing from the Grasshopper document?  Every time I save, close, and reopen, 
I get the error below.  Upon open, all of the DIVA components 
(Daylight Analysis, Materials) have disappeared and I have to remake 
them.  Really frustrating and time-consuming problem...  I am using 
Diva 1.9, GH 0.8.0066, and the problem occurs in both Rhino 5 64-bit 
and Rhino 4. 

Any ideas? 

Thanks, 
Marc

    I'm not completely sure... but it looks like one (or more) of the DIVA components isn't properly deserializing itself.  Thus, when the definition is re-opened, some of the chunks are missing (upon reserialization).  Unfortunately (if this is the case), there's not much that can be done except to go into the code and re-work this portion so that everything is properly deserialized upon saving.  Perhaps the developers could issue a quick patch to solve the problem.  Or maybe David has a better solution.

      Hi Marc,

      This is a known issue with only the legend component and will be fixed for the DIVA 2.0 release. I got all the errors you describe when I try to open your definition, but I am not able to repeat the error if I add the definitions and save them again. If I put all the DIVA components into your definition, then save and open it again they all open (except the legend component- whose function can be created on its own from some native grasshopper components). I am running 0.8.0066 with Rhino 4.0 SR 9. Please confirm you are using these versions and try opening the attached definition.
