Item1352: CompareRevisionsAddOn updated to use FSA architecture - eliminates problem with headers seen at the bottom of page and enables other enginers than CGI

CompareRevisionsAddOn does not work well with 1.0.4

In the compare screen you see two headers appended.

In the HTML source you can see that they are added AFTER the trailing /html tag.

CompareRevisionsAddOn is an old popular extension that I took over maintenance of when the original author slammed the door and left TWiki many years ago. It does all the rendering on its own and it has worked well since TWiki 4.0 only with some tweaks to the templates that comes with the addon.

But I am a bit stuck with this one.

I need some hints about how to get around it.

It is the Item923 "Adding two new fields to the default response header: Action and URI. read ExtraResponseHeaderFields for details" that has caused this new problem.

It is naturally the strange way the addon works that makes the 923 change not work.

I am hoping for a hint how I can either change the compare script or change the way it works so it does not have to render the whole thing itself.

For 1.1 I hope we can replace the current rdiff with the function of this addon. But for 1.0.4 we need this addon to work.

I can confirm the problem. Porting CompareRevisionsAddOn to FSA architecture solves the problem and make this extension usable with engines other than CGI.
