Subject Re: super_column.name?
Date Fri, 18 Mar 2011 21:17:37 GMT
Hi,
Just thought I follow up and mention that I was able to fix it.  I was calling super_column.name
in scala, which was accessing the name field in the SuperColumn class, and not actually calling
getName().  Thanks for the feedback, it helped.
