Grails flash scope acts differently with HTTPS -

Grails flash scope acts differently with HTTPS -

when forcefulness https through tomcat (or grails run-app -https), object stored in flash otherwise not null turns out null. i've tested on different environments , consistently case.

in below sample, foo executed first , foo.gsp submits bar.gsp

controllera { def foo = { flash.obj = myobj } def bar = { println flash.obj // null } }

not sure if flash scope should survive controller method foo bar why work without ssl?

any help appreciated!
