Segmentation violation when importing RooNDKeysPdf to RooWorkspace

Roofit and RooStats
1

Dear all.
I am having troubles saving a RooNDKeysPdf to a RooWorkspace. When I try to do it, I get a segmentation violation preceded by the message

Warning in TBufferFile::WriteObjectAny: since RooNDKeysPdf has no public constructor
which can be called without argument, objects of this class
can not be read with the current library. You will need to
add a default constructor before attempting to read it.
“Warning in TStreamerInfo::Build: RooNDKeysPdf: RooNDKeysPdf::BoxInfo has no streamer or dictionary, data member “_fullBoxInfo” will not be saved”

The full trace is appended below.
I also attach a revised version of the rf707 tutorial macro in which the problem can be reproduced in the root v6* versions.

To be clear: to reproduce the problem from the previous file you have to uncomment the line
// w->writeToFile(“TestingNKeysPerst.root”) ;

Hi,

This a known problem, due to the I/O of this class. We will fix it , hopefully for the next release

Hi,

I’m also interested in this feature, do you have a time estimate for when this will be available ?

Any update on this?
I have tried to import into a Workspace also a RooFormulaVar and it crashes as well. I have tried to switch to the latest ROOT but seems that the problem isn’t fixed yet. Is there any time scale on when ROOT will be able to write again such PDFs and formulas into a Workspace? It is an important feature that would ease significantly the coding of several analyses…

Thanks!
