bean throws NPE when key doesn't exist

Defect Minor Closed Declined Unassigned Benjamin Teuber Sat, 22 Jan 2011 09:57:23 -0600 Tue, 5 Apr 2011 20:46:42 -0500 Tue, 5 Apr 2011 20:46:41 -0500 Release 1.3 0 1 <p>The proxy returned by (bean) performs a bare invocation on the getter method without checking if it exists first. Fixed the bug by adding a long-hand constantly as the missing value for the map fetch. (constantly is not defined yet when core_proxy is read.)</p> <p>Also renamed the property map defined in bean to 'propmap' instead of 'pmap' to avoid ambiguity with clojure.core/pmap</p> <p>Beans aren't maps, and without any discussion of motivation it isn't clear that this change is an improvement.</p> <p>If bean was more consumer-friendly, people might use it in production more often. Don't. Reflection is slow. If there is a motivating use case other than REPL exploration for converting beans to maps, let's design something more performant targeted to that case.</p> Approval Test Global Rank Patch Code and Test
