Return null/undefined from find() when the component isn't found

[pward123]

Is there a reason that FlowComponents.find() throws an exception when a component is not found?

I have an existing project with modal dialog support that retrieves the template name to display from a session variable. I would like to add direct component support by doing something like:

{{#if isComponentModal}}
  {{> render component=template}}
{{else}}
  {{> template}}
{{/if}}

ModalDialog.helpers.isComponentModal = function() {
  return FlowComponents.find(App.activeModalName());
}

ModalDialog.helpers.template = function() {
  return App.activeModalName();
}

However, the find call is throw an error when the component is not found. Obviously, I can just wrap the find call with a try/catch block, but it seems strange to have find() throw an error in the first place.

Here's an example of what I'm talking about. I don't want the caller of openModal to know whether the modal is a component or template. Since the ComponentsStore is hidden, the only way to determine whether I'm dealing with a component is through find.
