Issue with CF9 - MG mixing up controllers from different sites

[Ryan Stille]

I'm having a weird issue. I run a couple sites on my workstation,
using Apache. I installed CF9 alongside my already installed CF8, and
changed Apache to use CF9. If I start up CF9 then hit either site,
that site works fine. But the 2nd site I go to never works, I get odd
errors referencing services that don't and shouldn't exist on that
site.

I finally figured out that when I go to the 2nd site, its using the
main controller from the first site. Both sites have a main
controller located at /controller/Contoller.cfc, and it seems
ColdFusion is getting confused.

When I change Apache back to using CF8, everything works ok. So its
either an issue with CF9 or my installation of CF9. I've checked a
couple things - "Trusted cache", "Save class files", and "Cache web
server paths" are all turned off. I've also stopped the server,
deleted all the files from the cfclasses directory, and restarted.

I've been working on this all day, I'm pretty much out of ideas. Any
suggestions?

Thanks,
-Ryan

are you using different application names in application.cfc/cfm ?

I just double checked - yes they are different.

[Bob Silverberg]

Is it possible that your install of CF9 somehow has an admin mapping of /Controller?  Sounds like some sort of mapping issue.

That is what it seems like. I checked the mappings, they are setup
the exact same way as CF8. I only have a couple mappings, one for
ColdSpring, one for ModelGlue, one for my components.

CF9 has added some more caching to speed up CFC instantiation so I
suspect you're running foul of that. There's multi-web / multi-site
setting and there's a CFC path cache setting, I believe (sorry for
being vague, I don't run CF9 so I'm going off memory of early builds
that I had access to).

clear both your template and cfc cache. I've found CF9's caching to be
over agressive even with all the cache options turned off, but that
usually cures the problem for me.

Chris what directories are those? I cleared the cfclasses directory.

Hi Ryan,

Chris is referring to the "Clear Template Cache Now" and "Clear
Component Cache Now" controls on the Server Settings > Caching page of
the CF Admin.

I did some experimenting, and was able to reproduce this problem with
a couple of simple test cases (if anyone is interested in trying this
out, email me off-list and I'll send them over). I set up two new MG
sites from the app template, and configured them both to run under
virtual hosts by changing all the paths so that the apps would run
directly in the webroot. I then added a different model component for
each, naming them Service1 and Service2, and wired one into each of
the two controllers using the "beans" attribute on the cfcomponent
tag.

At least in the scenario I set up, the the problem arose when enabling
the "Component cache" option in the admin -- when this was enabled,
the first site to initialize worked fine, and the second blew up, as
the controller from the first site was being used, and it was
referencing a CFC that did not exist in the CS bean factory for that
site. Disabling this setting resolved the issue, and both sites were
able to spin up. I didn't see you mention that you had disabled the
component cache, so I am presuming that will resolve the problem for
you.

It does occur to me, however, that this problem may well arise on
production sites (when more than one site is present on a server)
where it may be desirable for the component cache to be enabled. In
this case I would recommend a strategy of setting up a mapping for the
site, and using this mapping in all the MG paths. For example, instead
of referencing your controller as:

<controller id="Controller" type="controller.Controller">

Set up a mapping ("mysite", in this example), and use this instead:

<controller id="Controller" type="mysite.controller.Controller">

HTH,

Chris & Ezra, thank you. Turning off the Component Cache did fix the
problem. I guess that must be new in CF9, I wasn't aware of it and
for some reason I didn't even see it when I was looking on the Caching
page. I guess I skimmed through there too fast.

In my opinion Adobe should have turned it off by default, if its going
to cause issues like this.

Thanks again,
-Ryan
