The following patch fixes a problem with the Provider controller when it searches through the folders looking for providers.  If it finds a folder that doesn't contain a provider, rather than just ignoring the folder it throws an exception.  This is especially evident when you use SVN.  The folder name for SVN could be ".svn" or "_svn".  This code ignores any folders that don't contain a provider regardless of the name.

Thanks Henry.

I don't think my categories were nested heavily enough for this to show up.  But I have absorbed your fix into my code.  Thanks.

Since posting those first few mods I have also developed a PayPal Credit card payment provider and a replacement AddressProvider and TaxProvider.  I have also fixed the Provider Model for Tax and Address Providers so that I could develop my providers without destroying the Default providers that come with the Store.

If Gilles reads this and is interested in getting those providers working in the main project (if he hasn't already done it of course) I would be happy to prepare the patch.

The ShippingProvider is next on my list!

Stuart

Thanks!  it works a treat!
