    Error when upgrading to 2.3.0

    Hi Rusty

    I've an Merchello 2.1.0 with Umbraco 7.4.3.

    After upgrading to 2.3.0 I get following error when starting:

    INFO  Merchello.Web.UmbracoApplicationEventHandler - Attempting to initialize Merchello

    Tried following:

    • Upgrade to Umbraco 7.5.4 then Merchello 2.3.0 but error.
    • Upgrade to Umbraco 7.5.4 then Merchello 2.2.1 (this works I can access the Tree etc.) then Merchello 2.3.0 but error.
    • Umbraco 7.4.3 then Merchello 2.3.0 but error.
    • Umbraco 7.4.3 then Merchello 2.2.1 (this works) then Merchello 2.3.0 but error.
    • Deleted App_Data/TEMP, re-indexed Examine, copied merchello.config from Fast Track, ...

    Do you have any clues?

    Thanks
    Calvin

    What payment providers do you have installed?

    What is being reported is that something is trying to read from a resolver before Umbraco has frozen the "Resolution" singleton - which Umbraco does not allow.

    I've never seen it before but am interested as to how it might occur. Do you have another event handler that is doing something with a Merchello resolved provider (like a payment provider or notification provider) before Umbraco is started?

    Ha! Found it but it's super weird.

    I've a custom PayPalExpressPaymentController to do some additional stuff (we cannot use the Merchello.Web.Store atm).

    There I use the same attribute [GatewayMethodUi("PayPal.ExpressCheckout")] if I remove this attribute it works - no errors.

    If I re-add it the error occurs.

    So I think it gets somehow confused because the PayPalExpressPaymentController is there twice with the same Attribute?

    Edit: Renamed it to MySuperNewPayPalExpressPaymentController but error still occurs. So I think the problem is, that PayPal.ExpressCheckout is used twice?

    Edit 2: Also to mention that I don't use [PluginController("Merchello")] on my Controller...

    The [GatewayMethodUi("PayPal.ExpressCheckout")] is not required - it's only for the resolution. In you want to use it, you can change the alias to anything you want - e.g.

    [GatewayMethodUi("MyImplementationOfPayPal")]

    It does NEED to be unique in order to be used in the FastTrack starter albeit minor tweaking could get around it.

    The PluginController is an Umbraco attribute which basically allow one to put a controller into a specific area (and allows for locating views in the App_Plugins folder for the "area").

    So you could put views for a controller decorated with [PlugingController("MyPlugin")] in App_Plugins\MyPlugin\Views
