I’ve recently been working on a demo version of a project, and while I was working on the demo, a problem occurred that I hadn’t seen before.
I have a requirement that I need the conveyor belt to generate a component when it receives a signal, this component it has two sub-components and the three components generated have their own signals, I generate this component through the python script component.clone(). Since I can’t see the signals of this new component after I generate it after triggering the signals, I will re-open the signals window to make their signals visible, up to this point it’s all fine, however, next, after the component disappears and I close the signals window again, the VC gets stuck straight away before it closes it for me, and by this time, an error has occurred.
I clicked on the model again in the MODELING module, and nothing happened (normally it would have shown the highlight), and the next thing I couldn’t recover even if I reopened the file, so I had to restart the VC, but at that point, he would remind me that my floating authorization had stopped, and I would have to go and restart the authorization in order to reopen the VC.
From what I remember, I should be fine with this, so I opened VC version 4.8 again to re-open it, and I realized that this problem didn’t exist in 4.8, so I’m assuming it’s a bug that has appeared since the 4.10 update.
Attached is the error reported in the video:
