Hi Phani, Hmm… interesting. I think that you may be using the class in a way that we did not expect - I think that we intended it to store a struct/class rather than a primitive data type. I think that this should be an easy fix, namely that this assert (and perhaps others) need to be extended to read something like (std::is_base_of<DataType, T>::value || std::is_same<DataType, T>::value)
Would you like to try to see if that small change fixes the problem, or else would you mind please providing us with a full minimal test case that reproduces the problem? In the mean time you could also simply wrap your single double in a struct which should circumvent the issue.
