Error on Enumeration guessing where NULL values are present?

[jamesrwelch]

A user reports that the enumeration guessing is causing an error:
"Error in Import Process"

"We put together a small dummy dataset without any NULL values, and the Mauro Data Mapper was able to load up enumeration values for that. So as far as we can tell, it is the NULLs that causing the issue"

That’s odd cos we tested this exact issue when we were developing it

@jamesrwelch Please can we have the error log?

@jamesrwelch can you confirm what plugin versions are in use? I am a bit puzzled that the screenshot does not show a 'Calculate Summary Metadata' checkbox beneath the 'Detect Enumerations' checkbox.
