switch between template sets

Dear ZMS user and devels,


today i've tried to use a ZMS instance with different template sets - choosen 
by URL. 

I want to use a different template for mobile devices (not just CSS handheld 
based).

This won't work for me - if anyone has a better idea how i can provide 
different sets of ZMS templates for a ZMS site pls let me know this.

My idea was to put the different parts of the main template into a sub folder 
and use the aquisition mech of Zope - like:

my instance:	/zms1/
content path:	/zms1/content/

the "standard" template methods are located under
			/zms/
as usual.

I created a subfolder /mobile/
			/zms/mobile/

and copied (for first) the
	"standard_html***" methods into it.

(My target is to modify header and footer - if possible the float too - in 
this subdirectory to a optimized content flow for mobile users / devices)

1.)
If i try to call the url:
	http://example.tld/zms1/content/mobile/

i get a "Index out of range" in the content area of the page - but the teaser 
area (and other parts of the template layout) from the start page was shown.

2.)
If i try to call any sub page url - like:
	http://example.tld/zms1/content/mobile/e89/
the page would displayed - but without aquisition of my changes within
	/zms1/mobile/

3.)
If i try
	http://example.tld/zms1/content/e89/mobile/

i get the same error then under 1.) ("Index out of range").


here is the full zms-error:

May be someone could point me to a solution?

however...

many thanks for your time in advance!
best regards,


Niels.
