Subject Some Error Problem with Leteral Cache
Date Mon, 08 Aug 2005 00:21:41 GMT
Hello Aaron,
So far I am tring to use Torque with JCS Leteral Cache. But couldn't success.

I got the following error.
Would you explain what is the error mean in JCS ?
( looks like the torque MethodCacheKey tried to get hashCode and it make NPE. 
  My om and manager object has some problem for using cache update I think )
