Yellow screens when used with uCommerce: Unknown connection string. Name: '$(1)' about unicorn

[kamsar]

Take a look at the /sitecore/admin/showconfig.aspx page; it's likely both data providers are trying to patch the same thing and getting in each other's way.

Depending on how uCommerce handles the data provider (I haven't used it), you might need to make a subclass of its data provider and hook Unicorn into overridden methods (look at the Sql Unicorn data provider as an example here, it does exactly the same thing to the SqlServerDataProvider)

On a blank install of Sitecore 7.2 140526, and uCommerce 6, I get the following exception "Unknown connection string. Name: '$(1)'". We suspect it may be something to do with the fact that uCommerce items are also data provided and live under /sitecore/ucommerce

Can you point us in the right direction?

Thanks for the great module,
Steve

Hi Kam,

Upgrading my version of uCommerce solved the issue - my colleague told me that this is apparently fixed since version 6.1 of uCommerce. I was looking forward to getting into the nitty-gritty of data-providers but sadly my issue was solved quite easily :-)

make sure that sitecore read the unicorn congratulation the last.
p.s change the unicorn configuration folder name to start with zzz or such.
