Hey Andrew,

In this last version 1.2.1, a single Bundles.Reference causes the following error when trying to load the application. But I think that the problem is on the configuration of the Cassette.

I am sending the error message

Server Error in '/Atual' Application.
A StylesheetBundle with the path "~/Content/css/accordion.css" has already been added to the collection.
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.ArgumentException: A StylesheetBundle with the path "~/Content/css/accordion.css" has already been added to the collection.

Source Error:

Line 19:             // In production the content will be minified, but the files are not combined.
Line 20:             // So you probably want to tweak these defaults!
Line 21:             bundles.AddPerIndividualFile<StylesheetBundle>("Content");
Line 22:             bundles.AddPerIndividualFile<ScriptBundle>("Scripts");

I didn't touch the Configuration of the Cassette (this is a new project) so it is with the factory configuration. The only page that refers to a resource is the layout page with the following:

    Bundles.Reference("Content/css/home.css", "head");
    Bundles.Reference("Scripts/jquery-1.7.2.js", "head");
    Bundles.Reference("Scripts/knockout-2.1.0.js", "head");
<!DOCTYPE html>
    <meta charset="utf-8" />

No problem with the previous version (1.2.0).


andrewdavey commented May 9, 2012

I wonder if the CassetteConfiguration is somehow getting called twice? Can you put a breakpoint in and see how many times it's hit?

danfma commented May 9, 2012

Ok... I will check that!

danfma commented May 9, 2012

I will check again later but apparently the configuration is not been called twice. But the error has gone, somewhat. I will check with more details as soon as I can. :)

Have you tried upgrading to the v2 beta? The bundle collection initialization was significantly improved and should fix problems like this.


andrewdavey commented Sep 10, 2012

v2 has been released. Does this fix the issue?
