Not sure if this is a bug or a work in progress issue.

Andrei and the team, i am not sure this issue is due to an unfinished work or it is really a bug.

it is in Change Set 54316 and has been there since the last 2 or 3 chagests as well.
the same thing happens as well when clicking on any category that displays products (categories with sub categories only work fine).

clicking on a product, causes an error as follows :



Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: The 'Weight' property on 'ProductVariant' could not be set to a 'Double' value. You must set this property to a non-null value of type 'Decimal'.

SOLVED: Database type mismatch.

the Weight datatype is defined as Float in the database and as decimal in the Model and code.

Changing it from float to decimal in the db solves the issue.

thanks.

need a little help here with "The 'Weight' property on 'ProductVariant' could not be set to a 'Double' value. You must set this property to a non-null value of type 'Decimal'.

i switched from godaddy to softsys, they restored my db and i'm trying to install v1.7 but run into this error. i'm not familiar with the db, if someone could point me to the correct location in the db to change the "float" i would appreciate it.

fyi - godaddy db was sql server 2005 and softsys is 2008 (if that makes a difference).

there is a file upgrade.sql in the documents folder. run it against your db. it'll add and correct everything.
