In the model properties for composer plugin outlet “composer-fields-below”,

I could not find the property of model object which says whether the composer is being used for creating a topic, or editing a topic or being replied to topic?

I’m not sure I follow where you’re looking at the model, but the model for the composer component has an `action` attribute. That’s what you’re looking for.

When I try to inspect the ember component, I find the action to be null.

In the above screenshot, I inspected the properties for the editor composer. The action is null.

I surely might be doing something wrong, or looking in wrong component. Can you please tell me which component did u inspect?

Why do I need to know if the composer is for create topic or replying?  
Because I want to add a custom field in composer, which will be used only when creating topic, not for replying..

Thanks Joe,  
I was able to find the action in

`component.model.action`
