Drag and Drop is not working !

Hi,

I could not map a context node from the component controller to the view controller using the drag and drop feature. I tried to restart the NetWeaver, but the issue is still there.

what could be the problem?

And, is there any way to map the context between components other than the drag and drop?how?

I'm using NWDS 2.0.17

Appreciate your help

Thanks,
