arcgis desktop - ModelBuilder not adding output feature class to Table of Contents?

I'm trying to create a tool in ModelBuilder that will take a new point from a user, create a feature class for this point and display it on a map.

What I've done is:

1. I've created a feature class for a point-like feature in ArcCatalog.


2. I've prepared a really simple model in ModelBuilder, that starts with a feature set variable (which takes the feature class as a schema and symbology file). The variable is marked as a parameter.


3. Next I'm using the Copy Features tool that takes the variable as input and saves it as a feature class in my scratch workspace.


4. The output feature class is marked as a parameter with the 'add to display' option.

After the module is run I get a shapefile in my scratch workspace. I can add it manually to TOC and it contains the selected point. However no matter what I do, I can't display it in TOC automatically after the model completes.

There is a known issue described in several places that doesn't allow to display newly created layers in TOC when model finishes with the 'add to display' option. However there's a quick workaround, which is to mark the output layer as parameter. In my case it doesn't work.

I'm using ArcGIS for Desktop 10.1 on Windows 7 x86_64.
