Oblivous caching: DynamicVariable >> #default
by Marcel Taeumel 31 Jan '15

31 Jan '15

Hi, there! After calling #value:during: for a dynamic variable, the #default result is cached in the env variable of the process. Changing the result of #default will have no effect on #value until the process is killed... I think, this is wrong... :-/ Best, Marcel -- View this message in context: http://forum.world.st/Oblivous-caching-DynamicVariable-default-tp4802924.ht… Sent from the Squeak - Dev mailing list archive at Nabble.com.
