I switched to database session store and the problem went away but I'm
still curious as to why it occurred in the first place.
Here's my action. There are no calls to any other controller
methods. In fact search for "session" shows it does not occur
anywhere in my controller. My controller inherits from
ApplicationController so there's nothing else added by me.
when strategy==Strategy.PCR: PCR.new(:strategy=>strategy)
when strategy==Strategy.PCRtm: PCRTM.new(:strategy=>strategy)
when strategy==Strategy.GSD: GSD.new(:strategy=>strategy)
when strategy==Strategy.GSDtm: GSDTM.new(:strategy=>strategy)
flash[:notice]='Design has been saved.'
flash[:notice]="Error saving design."
render :action=>'new' and return
