Perspective Drag and Drop Error

Ignition

This is present in Ignition 8.1.1 Nightly

When dragging a component onto a view as error occurs in the designer console:

It only seems to occur the first time you drag something onto an opened view. Subsequent drag and drop events don’t raise this error. It doesn’t seem to impact any functionality just a large red error in the consol.

Thanks for reporting this.

I’m pretty sure we’re already tracking this issue and waiting for a fix from TeamDev…

Not a problem. Just wanted to get info out so you guys know what is going on. That is the beauty of public betas and nightlies.
