An error occurred when trying to create a controller of type 'SevenSpikes.Nop.Plugins.AjaxFilters.Controllers.Catalog7SpikesController'. Make sure that the controller has a parameterless public constructor.

Hi, I Just Installed SevenSpikes.Nop.Plugins.AjaxFilters and SevenSpikes.Core when i am using the Filters i am getting an error stating "Loading the page failed" and in the log file the error shown is "An error occurred when trying to create a controller of type 'SevenSpikes.Nop.Plugins.AjaxFilters.Controllers.Catalog7SpikesController'. Make sure that the controller has a parameterless public constructor".Can anyone let me know how to fix this issue

Hi,

Have you made any changes to the constructors of the nopCommerce controllers? If you have please use property injection instead of constructor injection.

Hi, Thanks for your response can you please let me know how to use property injection  in detail with an example.However i didnot made any changes to the constructors of the nopCommerce controllers

Hi,

Here is an example:

private IMyService _myService;

public IMyService MyService
{
    get
    {
        if (_myService == null)
        {
            _myService = EngineContext.Current.Resolve<IMyService>();
        }

        return _myService;
    }
}

Hi, i just added some extra methods to the productsservice file so do i need to implement the property injection in Products related files

Hi,

There are no problems if you have added new methods.

If you have modified the constructor of the ProductService you should revert your changes and resolve the dependencies using property injection.
