When restoring a 7.9 backup to Ignition 8, I wasn’t able to open one vision screen (neither in the designer nor in the client). I thought the problem was this script in the “InternalFrameOpened” event: ```auto system.gui.getParentWindow(event).getComponentForPath('Root Container.txtUser').requestFocusInWindow() ``` As I couldn’t open the screen in the designer, I had to modify it in 7.9, and import it again. But even with the new import, it doesn’t seem to work. In any case, IMHO, a bug in a script shouldn’t be able to break the designer interface. ```auto 08:42:15.494 [AWT-EventQueue-0] ERROR com.inductiveautomation.factorypmi.application.model.WindowCache -

Apparently it's this issue, though I don't know why I didn't get the latest nightly this morning ... > [@\[FB12303\] Unexpected parsing error during binary deserialization](http://forum.inductiveautomation.com/t/fb12303-unexpected-parsing-error-during-binary-deserialization/21828): > > I have a couple windows from a 7.9.10 project that was imported into 8. There isn’t anything special about these windows (power tables, templates, buttons, script, etc.) that stands out to me from the 20-30 other windows in the project that upgraded fine. Any ideas based on the error below? Or do you need an export? I’m getting this both in the designer and launcher. 12:36:08.509 [AWT-EventQueue-0] ERROR com.inductiveautomation.factorypmi.application.model.WindowCache - Unable to open windo… ---
