Hi,
I have a may be weird behaviour in the menu items of my module. To bring it down to simple code I foo-bar-ed it on [1]
To describe it in a few words: In my modules-ui I define some paths/routes like /foo, foo/list, foo/add, foo/%bar/delete, foo/%bar/edit ...
foo/list and foo/add are used to show a list if bar-objects or to open a form to add a new one using simple _form()-hooks.
when editing, deleting or cloning an existing bar object a callback function is used to create the form who takes the bar-object as input - provided by the %bar -> bar_load()-hook
As long as foo/%bar/... items are not defined in my menu()-hook bar_load() is never called, but as soon as foo/%bar/... items are added to menu(), bar_load() is called several times (as often as menu-items with %bar exist) even when I request for foo/add or foo/list (which do not use %bar in any way.
Is this the intented behaviour? Why and which element calls the %bar bar_load()-hook even when my URl request does not fit the path-definition (foo/list instead of foo/%bar/edit -> I have no foo/%bar or foo/%bar/ defined)
May be I still do not understand Drupals architecture and Hook-system in a right way?

Hi Marco,
I only skimmed your message, but it looks like you might be hitting a known issue:
http://drupal.org/node/1471554 (see also: http://drupal.stackexchange.com/q/38987/633)
The simple answer now seems to be to implement caching in your loader function.
Thanks,
Andy
