Is pickPoint deprecated?

Something that seems to have worked previously for me Alpha2, is now acting weird in beta 3.

I am working on picking up objects created when something in the scene dies and drops items.

previously I used.

function sceneWindow2D::onMouseDown( %this, %mod, %worldPos, %mouseClicks )
{
        //lets get a list of all the objects at the clicked point in the t2dScene
        %objList = sceneWindow2D.pickPoint(%worldPos);
        //lets get a count of how many objects in the list
        %objCount = getWordCount(%objList);
        echo("objects at " SPC %worldpos SPC ":" SPC %objCount);
       //loop objects removed to keep post short
}

now in my scene when I click anywhere I started getting this in console.

shootemtest/main.cs (68): Unknown command pickPoint.
  Object sceneWindow2D(2198) sceneWindow2D -> t2dSceneWindow -> GuiControl -> SimGroup -> SimSet -> SimObject

has pickPoint changed, or am I just using it wrong, I'm pretty sure this used to work for me?

Thanks in advance.
