Null Exception Error
Designation Repository class
Judging based on limited information provided.
Simply put it means that you are trying to use something that doesn't exist.
Essentially this is returning a null value.
Without better question can't provide further help
I tried to fix using 'KMeans' object has no attribute 'labels_'
still I coudn't solve this error. Please help me.
You are confusing classes with instances.
You want to access the attribute of an instance, but you try to access it at the class where it does not exist.
I'm accessing iron:router in a helper which builds breadcrumbs, but oddly I'm getting two objects returned when I do this:
console.log(typeof Router.current().route.path(this));
I get back:
object
string
The object is null btw...
Does anyone know why? I think it has something to do with reactivity but I don't know where to look to begin.
I don't really know the answer for this, but easiest breadcrumbs are Iron.Location.get().path.split("/")
While this is not a direct answer to your question, this tutorial covers a lot about iron:router: http://kukuruku.co/hub/javascript/meteor-how-to-build-a-todo-list
I'm getting undefined reference to KDevelop::IPlugins. I know this means i'm missing the libary but I'm not sure which library this is. Where would I find this .so that I am missing?
KDevelop::IPlugin is defined in libkdevplatforminterfaces.so ("kdevplatforminterfaces" to cmake).
i sometimes get an error with the UpdateModel function.
However, i can't seem to locate the exact message which field(s) is/are causing the problem.
For example this one:
"The model of type 'Enquete' was not successfully updated."
it has an innerexception of NULL, and no further description. Is there a way to find out what is causing the problem?

EDIT:
i see this in my output window:
"A first chance exception of type 'System.InvalidOperationException' occurred in System.Web.Mvc.dll"
Steve Sanderson has a wonderful article on using the MVC source to help you debug your application.
I think this will help you get more info.

Just a wild guess: You are trying to bind null to a value type. Check in your model for int, float, DateTime, structs, ... data types that you try to bind to null.
I was getting this type of exception and from my experience i got what was causing it...
We have one primary key field or identity field in the entity...
If we try to display that field in the view using html control like text box and all then at that time updateModel throws exception
otherwise it wont throw exception
Use TryUpdateModel instead. It won't throw exception, but then you can inspect ModelState for errors.
I know it is late but to help others.
