[TYPO3-shop] PIDitemDisplay type=pid not working

[Claude Unterleitner]

Hello,

It's my fist onlineshop with tt_products. Almost everything worked fine
inspite of this:

I don't manage to get work PIDitemDisplay with the setting (manual, page
16):

# If you set the type to pid then the pid of the record will be used.
PIDitemDisplay {
10.type = pid
}

I use Typo3 Vers. 4.2.8 and tt_products Vers. 2.6.0

I tried almost everything. I put the code both under TS Setup as TS
Constants. I use the static template "TS Shop System Old Style".

Does anybody have an idear? Have I forgotten something?

Thanks,
Claude
