Folks, I am linking from page A to page B, and back again. When I go from A -> B, the B_controller.rb runs fine, and the page renders properly. But, when I go from B -> A, the A_controller.rb doesn''t run again, so the array (@A) is nil (which causes a problem). Should the controller run each time the page is accessed? Any ideas?

I have an Order model with a ''status'' column. What I want to be able to do is validate that the status of the Order is not completed before it is allowed to be deleted. I tried the following method in my Model, but it appears that this only works for an :update or :create on the record. Anyone know how to do this, and if it should be in the model or the controller?

Hi all, I had posted about MCA support for Intel64 before. It had only a function to log the MCA error data received from hypervisor. http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00876.html I attach patches that support not only error logging but also Page Offlining function. The page where an MCA occurs will offline and not reuse. A new flag ''PGC_reserved''

I would have sworn that someone on the list had a way to Xenify a stock RH kernel but I was not able to dig it up on the archives. If this does not exist I am sure it would be a nice addition to Xen to be able to patch and build some kernels that are compatable with some of the popular distributions. -- Alvin Starr || voice: (416)585-9971 Interlink Connectivity ||

Hi, I want to be able to have several layouts within each other so that I don''t have to keep repeating the layout code for one, in another. An example would be having a layout for the title of your web page and then having an embedded layout for the body portion in which the HTML for whatever view gets displayed. Is this possible?
