getCalculatedBaselineMeanValue is the wrong logic here, it is a convenience method that will only calculate the mean (it assumes the low and high are null). instead, we want to pull the low and high values up out of the database into the composite object that is fed to the cache loading mechanism, and call the getCalculatedBaselineValue_helper method directly to compute the derived value based on the percentage, the min/mean/max choice, and the current baseline value.

rev1881 - pull the min/mean/max values up out of the database when inserting baseline data into the alerts cache;
properly derive the calculated value that needs to be alerted on by using the baseline option (min/mean/max) along with corresponding baseline value;

confirmed this *is* an issue on 1.1

QA Verified, measurements on min/max of baseline can be created in 1.2 w/o occurence of NPEs.
