Hi guys, I was playing with Play Framework and Objectify, then I hit this problem. Whenever I add @Cached to any entity, the entity can't be put. The detail is here: http://groups.google.com/group/objectify-appengine/browse_thread/thread/de298fe07741cd53
Jeff Schnitzer suggested me to try executing plain SystemProperty.environment.value() in my Play code. And it indeed throws: Internal Server Error (500) for request GET / Execution exception (In /app/controllers/Application.java around line 14) NullPointerException occured : Name is null play.exceptions.JavaExecutionException: Name is null at play.mvc.ActionInvoker.invoke(ActionInvoker.java:228) at Invocation.HTTP Request(Play!) Caused by: java.lang.NullPointerException: Name is null at java.lang.Enum.valueOf(Enum.java:236) at com.google.appengine.api.utils.SystemProperty$Environment $Value.valueOf(SystemProperty.java:70) at com.google.appengine.api.utils.SystemProperty $Environment.value(SystemProperty.java:91) at controllers.Application.index(Application.java:14) at play.mvc.ActionInvoker.invokeWithContinuation(ActionInvoker.java: 541) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:499) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java: 475) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java: 470) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:158) ... 1 more I want to submit this to Play community, but I think it's more to GAE. Or should I post this there? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
