What you are calling BioC 2.3 isn't the release version. You have a version of AnnotationDbi that was devel somewhere between 2.2 and 2.3, but had been updated to 1.4.3 by release. > The first example (on the mailinglist) was a bad one (sorry Jim). > As I mentioned, the error first appeared with the latest releases and > causes the pipeline to break. > > Jim already suggested on how to proceed and I will follow that but can > you nevertheless tell me the background for this error? > Have there been changes in the annotation packages? This information > would help me to investigate and check the remaining pipeline-code. So to answer your question, the change that affects you here wasn't made to the annotation packages, but to the AnnotationDbi package. There is a function called .checkKeysAreWellFormed() that, well, checks to see that keys used for lookup are well formed (e.g, there are no NA or NULL values and all keys are character), and more importantly returns an error message that clearly states what the problem was. The second point is more important than the first, as obscure error messages tend to eliminate all possibility that end users might be able to self-diagnose their problem.
