scriptJob -attributeChange problem on CV

[vilbur]

Hi all, 
I would like to create scriptJob which will detect move of vertex on polygon object and then run function. I found that I can do it with -attributeChange flag. But my problem is that it works only if I edit attribute of CV in channel box. When I move vertex in viewport by move tool, nothing happen. Attribute is changed, but scriptJob doesnt detect it. Maybe xform can be better, but i dont know how to use it togerher with scriptJob.
Do u have any idea how to detect change of vertex position with  scriptJob?

You want to make a node. Script jobs get suspended when maya updates the dg s you cant use this to any other effect than to notify a gui, sluggishly about change. In effect script jobs do very little useful stuff beyond GUI work.* Also tools don't fire attribute changes in the nodes they manipulate.

So now for any sane solution we would need to know a outline of what the function does.

*In fact theres a few rules of thumb that shows your doing something wrong. Using a scriptjob is one of the most clearest indicator that your doing something you probably should not.
