Example in CompoundRootAccessor: ognlContext.pushEvaluation(new Evaluation(ognlContext.getCurrentEvaluation().getNode(), o)); What I believe are the related changes made in OGNL 2.6.0: (Full info under http://www.ognl.org/2.6.0/ReleaseNotes.html) Ability to turn off evaluation tracing for speed reasons. This is an effect of reimplementing the way indexed access is done. Evaluation tracing overhead is about 2x slower than without so this can be very significant. Keep track of whether to store the last evaluation or release it (if tracing is on). The default is true (keep last evaluation) for compatibility but having your code that creates contexts default this to false is recommended if you want to keep memory usage down. These get created a lot and if you don't have a good reason to remember the last Evaluation after an expression is run then you should be letting them get recycled. An alternative (I know Måns Klercker needs this) is to use the last Evaluation and then call OgnlContext.recycleLastEvaluation() to let it get back into the pool. OgnlException now stores the root evaluation that caused an exception. This is regardless of the setting of keepLastEvalution in the context (if tracing is on), but this will not occur unless the evaluation tracing is enabled. --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.
