How to detect load window?

Hello i’m using several services where I use load of content method. Each of it shows own loadController to show loading window.
How to detect load window is already exists to prevent show new of it?

I’m interested in this too.

I don’t know if there is a way of doing this the correct-easy way.

But now that I think, I’d nest a LoadComponent inside a Subscription, I’d break the Subscription whenever the content is ready. Make sure the subscription and the LoadComponent are the same time length.

So anybody know about solution?

Hello, I did not understand your question. Could you elaborate it better so I can help you?
