Re: [rules-users] Check for null entry in collection before iterating

I'd dearly love to hear some good argument why null in a List<Things> is good coding practice (note: I'm not asking for "best practice"). - Compare these two sentences: He looked into her eyes.... He looked into her eyes. It's pretty obvious that the ellipsis indicates a planned absence of words, whereas the second sentence just shows a void, or no void, at its end. (Or: lover or typo or oculist.) What I'm trying to say is that a null planned to show a special case is indistinguishable from the null that happens due to an error. Processing "from" while covering null is just postponing the detection of an error - if you are with me that null shouldn't be there in the first place. But, yes, you can test: list contains null should tell you whether there is a fly in the ointment. -W On 29 April 2013 15:28, dcrissman <dcrissman(a)redhat.com&gt; wrote:
