Contour node initialization

Hello, noticed a strange bug which happens sometimes with the contour node.

When i start my patch it doesn’t return any value (the texture in/out are correct i can check that, it just doesn’t returns the blobs).

If I open the contour help patch and then close the main one starts to output data.

Any hint appreciated

Also, the blob id pin for contour is called ID, which conflicts wich the Node ID output, would be nice to have it changed too :)

toooo late and no idea about the first problem anyway.
but fixed the pins name for beta>21, thanks.
