Subject Re: how to use the persistence flag in addAttribute?
Date Wed, 01 Apr 2009 02:13:16 GMT
Could you show us the codes that how you get the Dictionary GBean from
Kernel ?
I think you should get the Dictionary object via ProxyManager, so that
Kernel will monitor the changes of dir property.
Thanks !
