Actually I did not override controller I override a generic route.

My plugin has a custom view engine as following:

CustomViewEngine : ThemeableRazorViewEngine

The plugin has a view file called CategoryNavigation.cshtml which also exists at Views\Catalog\CategoryNavigation.cshtml
Now if I delete the files the error reported by the view engines are as following:



As you can see the first searched location is the plugin folder. If the file exists in the plugin folder it is displayed without any error. But if the file exists both in the plugin folder and in Views\Catalog  then the view from Views\Catalog  is rendered instead of the plugin folder. Tho that is way down in the search location.
Any idea what might be causing the issue?

As the CategoryNavigation.cshtml view exist in two locations so the viewengine confuse which one it will show. The solution is write

return PartialView("~/Plugins/YourPlugin/Views/YourView/CategoryNavigation.cshtml", model);

at controller. Where from the view appear. I mean at

public ActionResult CategoryNavigation(int currentCategoryId, int currentProductId)
{
...................
}

{
...................
}
I do not think the view engine is confused! A file can exist in multiple locations and the first searched-found location is returned. That is how the MVC works.

I am not having any error in the application. I just need the view rendered from the plugin. I am trying to override the left category section from a plugin. That is why I do not want to modify the Catalog controller either.

Ok let me understand your requirement first. If you want to show "CategoryNavigation.cshtm" view from your plugin then at _ColumnsTwo.cshtml you may write

@Html.Action("YourCustomCategoryNavigation", "YourPluginController", new { currentCategoryId = currentCategoryId, currentProductId = currentProductId })

The "YourCustomCategoryNavigation" method will have the same functionality as the default one but it will return

return PartialView("~/Plugins/YourPlugin/Views/YourView/CategoryNavigation.cshtml", model);
