"There is no active view" when trying to use MEL command 'lookthru'

[Anonymous]

I am trying to look through a particular camera when doing a playblast command from a script.  The object is there, but when I call lookthru, it gives me the error 'There is no active view.'  Here is what script looks like.  Any idea what I am doing wrong?  I don't really have experience with cameras yet.

if(`objExists Playblast_Camera`)
{
    lookThru Playblast_Camera;
}

... I also tried this, get same error:

string $camView = `cameraView -camera Playblast_Camera`;
lookThru Playblast_Camera $camView;

For anyone else who runs into this, I solved it by not using 'lookthru'.  Instead I set all the cameras' renderers to off except for the playblast camera:

string $cams[] = `lsType("camera")`;

for ($cam in $cams)

{

    catchQuiet(`setAttr ($cam + ".rnd") 0`);

}

catchQuiet(`setAttr ("Playblast_Camera.rnd") 1`);
