Hi Simple copying object from a view to another view causes the designer to freeze forever and I have to close the designer from the task manager. Tested in Ignition: 8.1.4 8.1.8 8.1.9 ![copy](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/7/d79d6561ab22e2e16ee775982bc0b3b2b0845e45.gif) ---

Can you try using Jstack to get a thread dump while in this state? I made a ‘bad’ test window with several hundred (deeply nested) coordinate containers, and while performance was pretty terrible, it didn’t take more than a few seconds for the paste to complete. ---

I don’t know how to do that. Can you explain a little bit on how to do that? Or I can export view to you so you can test on your side. ---

Posting/DMing the view would probably be easiest 🙂 To use JStack you’ll need to have a JDK11+ install on your system; the Ignition runtime isn’t a full JDK. ---

ive had this happen to, it might be that it was pasted from a flex container to a coordinate(in either percent or fixed mode) or from percent to fixed container? ---

No, both are coordinate container. ---

Yes both use fixed mode. I just want to combine several diagram into one bigger page. Now only possible way for me is to import the as embedded views. ☹ ---

Thanks for the report; I was able to replicate with your provided view. From what I can tell, the Java side of things is ‘blocked’ on the event dispatch thread waiting for some ‘frontend’ code in the design session to return a result. My guess is there’s something in that frontend code that’s not scaling well to the number of components you’re trying to copy at a time. As ever, for a workaround you could probably copy the JSON structure directly (or even Shift + Right Click → Copy/Paste JSON) to copy the elements from one view to another. ---

Thanks, please update me when fix come out.
