Subject Re: Iterating through a BinaryObject cache fails
Date Fri, 01 Jul 2016 16:26:54 GMT
Hi,

Is the question somehow related to your previous quiestion, entitled Error
while loading data into cache with BinaryObject as key field ?

I see the same eexception here.

How do you fill the cache with data ?
