What is the sequence of paste operations to a new document?

[Kyudos]

I've set flags and data in (documentLockModeChanged) COPYCLIP to allow me to veto PASTECLIP to another document if my custom objects are involved.

However, when I go to paste into a new document, before I even hit PASTECLIP, I get into the subWorldDraw of my custom objects? This is actually causing a crash - surely I should be allowed to decide if a paste will go ahead before Acad starts trying to draw my stuff?

I see i get into commandWillStart before the crash - but I can't veto PASTECLIP from there (well, not as easily anyway).

What actually happens when I go to paste something in a new document? And specifically, how much of that occurs before PASTECLIP is triggered in documentLockModeChanged?

Hi,

Is it possible for you send a sample project demonstrating your problem, and objective you are trying achieve. I'm sorry I'm not able make out from your description, it is tough to tell what happens in generalized way when a pasteclip is performed this has to be dealt case by case, and, we don't access to High level design CCP implementation, If you can provide a sample project and instruction to build and reproduce the behavior, we can try to persuade concerned development team looking in to this, considering business requirement you have in hand.

Within my knowledge I can say CCP in AutoCAD implements Clipboard mechanism of Windows.

I've worked around this for the moment, preventing PASTECLIP of my objects to different documents within the same instance of AutoCAD. I haven't worked out cross-instance pasting yet, but I should think that would be sufficiently rare as not to present a major issue to start with.

Thanks for your attention.
