In the panels area, there is a part called ‘selection rules’, and other areas that can control arguments, or contexts, or many other items.  You might try digging through the panels area for your culrit.

Subject: [development] The Mestopheles path


I've spent a couple days at this point trying to discover how something is being done, without much progress. I'd walk through it in debug, but the environment for this site is wamp and I'm equally unsuccessful getting phpStorm and xDebug to play nicely in Windows, so far.

A D6 site using panels.  A view producing a block. The panel page loads the block and overrides its path (well...technically not, but that's what the setting says) to be domain.com/music

Have a module that implements pre-process, as well as registering a callback. The path in the callback is /music-xml.   The pre-process implementation checks for arg(0) containing music-xml. The module registers its templates directory, which contains a template for page-music-xml.tpl.php.   When invoking /music, the result is the callback or music-xml fires, arg(0) contains music-xml, and the template fires. The browser path, meanwhile, still says /music

The problem is that I need to change the content type used in the view from music to something else, at which point it all breaks...arg(0) shows up just as music then, not music-xml.

I've grepped the code, exported and grepped the db, clicked all the clickables (I think) in panels, check path aliases, strongarm ... I can't figure out how it's being done.


I am a non sequitur. Beware, the contents were packaged where peanuts are processed.
