Need Thumbnail warnings explanation

Misha Zaslavskiy

Hi,

I have a skill function that processes layout view in all cells of given OA library. At the end of operation I got multiple warnings like below, as many as the number of cells in my library:

*WARNING* Thumbnail window was requested, but has already been closed

I'd like to fix them as this skill code will be used by other designers but cannot find what is the reason and what I do wrong. What I've tried so far was to manually create thumbnail with hiGenerateThumbnails() function and double check that every view and library object are properly saved, closed and released: dbSave(cv), dbClose(cv), ddReleaseObj(cellId).

Any hint or explanation of this warning root cause will be greatly appreciated.

Thank you,

Misha

  • Hi Misha,

    Are you using DesignSync from Dassault MatrixOne? I found a lot of references to this caused by a trigger in their system attempting to close windows when it shouldn't. If you are, my  understanding is that they've fixed this problem or have a patch for it, and so you might want to contact their support for an updated version. This seemed to be the vast majority of reports of such an issue.

    If you're not using DesignSync, I suspect you will need to contact Cadence Customer Support so that we can investigate precisely what you're doing that is triggering this.

    Regards,

    Hi Andrew,

    Thank you for your idea, I haven't thought about this possibility. DesignSync is available in my system but should be disabled for this project. Maybe there are some leftover setups that trigger this behavior.

    I will try to experiment with version control setup and contact support if unable to resolve it myself. 

    Regards,

    Misha
