Pivot node not working correctly? about hits HOT 5 OPEN

This error message tells you that you have to compute the domain of the column. 
You
can use the Domain Calculator node to achieve this state.

Please also note that the result might be not satisfactory for you. You have to
reorder your data to have the values in the ObjectIndex in ascending order for 
each
group.  (Actually I do not know how to do this in KNIME. This might be a good 
new
feature to support.) In this case it creates too many groups and not what you 
might want.

I am going to create the node for reordering this kind of data do you have any 
ideas
what are the important features of it? Do you see other solutions to this 
problem?

PS.:It might be useful if questions like this would go to the user's forum
(http://groups.google.com/group/HiTSusers). If you want we can continue our
discussion there.

I had typped an answre but somehow it seems that it has now disappeared. I am 
moving
this to the user forum as per your request.

Could you check whether the examples, descriptions are interpretable, clear?
