Converting an Application from Fusebox 3 to Fusebox 5.5 (Part 3)

I have now got several circuits working in my application and as a result have developed a kind of methodology for doing the conversion.

As wel as the items mentioned in the earlier posts there are a number of changes required.

Content Variables and Layout

The first is that since my fusebox 3 application was using the nested circuits I have to put all my display includes inside a cfsavecontent tag. For the moment I don't want to make any big cahnges to the application and it does not use MVC so I can't make use of the do facility to put the output of those fuses into the content variables.

Fusebox3 put everything into a variable called fusebox.layout which was in variables scope. Since I don't have easy access to variables scope I decide to use a request scope variable which will be available in my circuit CFCs. In my case I am using request.page.content mostly because that is the name used in some applications I have.

The same variable has to be used in the layout files and in the fbx_layout I actually have to include the file as it is no longer done automatically for me.

Fusebox Variables

There are several places in the code where I have used Fusebox.Fuseaction and this needs to be changed to MyFusebox.OriginalFuseaction. To make this work I also need to add the argument tag to every method in that needs it.

Attributes Scope

All my existing fuses expect to find the data that was in form or url scope in the attributes scope. By adding a line in the prefuseaction I can copy that from the arguments in one place.

I hope these notes are proving useful to anyone planning a similar conversion. Do let me know.
