This almost belongs in my sarcastically titled, “Meaningful Error Messages ..” series, but as it has traceable causes, I thought I’d write something up on its most frequent causes (I meant to write this up a few months ago, but it slipped my mind (find it in your heart to forgive an ol’ developer) and now I think it’s time the world knew).
‘DML currently not allowed’, what could that mean? Well it means that DML isn’t allowed. And that it’s not allowed right now, but with the slight promise that given time, it will be allowed. Often in the past, hoping against hope, I kept on pressing that button/link/onclick-area, but the cloud never changed its mind. With a sigh I constructed the Google search query and began trundling through the results.
