VM:1124 + J1.5 (latest SVN)
I've created a Product Type with 2 Parameters.
When adding value to a product, those param values are not saved.
Looking deaper in the Template (Browse) files, I don't think nothing is really loading them...
I haven't tried it (a bit busy this month), could you please try rev 1133 lots were fixed.
Sorry, but not even with 1155
