JChem 5.6 go 6.1 Upgrade (MSketchPane::setPiece)

So I have an issue with my code that works on JChem 5.6 but not 6.1.  It deals with MSketchPane::setPiece().  What exactly does it do?  The API documentation seems sparse as to what it does.   We previously have this code snippet:

molEditor_.setPiece(_rgrp); 

where molEditor is a MSketchPane and where _rgrp is equal to:

r-group

  1  0  0  0  0  0            999 V2000

    0.0000    0.0000    0.0000 R#  0  0  0  0  0  0  0  0  0  0  0  0

M  RGP  1   1   2

M  END

 

We had this hooked into a java swing MouseAdapter where the mouse cursor turns into R1 which then allows the user to put on the structure.

With the upgrade to 6.1, the same code now replaces the entire structure (see attached picture)... similar to setMol().  What method should I be using now?

 

Should I provide more information for the above question?  I'm not sure if I'm being clear as to what I'm trying to do.

Hello Kongar,

I've looked into your issue and found out that it is indeed a bug, setPiece(mol) should not replace the molecule, and the bug has been in since version 6.0.

I put a ticket into our bug tracking system, and we will inform you when the bug has been fixed.

Thanks for looking into this, Tamas.  Is there a workaround that I can use?

Sadly, on the public api there is no other option with the same behavior.

Is there a private API, then?  Maybe I can use Java Reflection to force private methods public.  A hack will work fine at this point.  

We delayed upgrading from 5.6 to 5.12, because we found a bug during the upgrade, and we waited for the fix to show up in 6.1.   Now there is another bug that may block us from upgrading yet again...

I am happy to inform you that the fix was included in Marvin version 6.1.3 ( It can be downloaded from our website. )

Best Regards,
