1.1 Exception: io.github.andrewauclair.moderndocking.exception.DockingLayoutException

Open tlf30 opened this issue 7 months ago • 4 comments

Hello @andrewauclair,

I just updated to 1.1, and am seeing this exception. The exception is thrown on app statup.

And when attempting to pin to the side, I see the same exception and the dockable disappears.

The docking overlay is rendering odd too:

After restarting the app so it generated a layout xml. I also get this error on startup now:

EDIT: This is the contents of the generated XML (Yes, it is cut off like that in the file)

Looks like one of the anchor strings is likely null when loading an old layout. Auto hide appears to not work at all because I have the code commented out... I'll get these sorted out today in a 1.1.1 release.

andrewauclair avatar Apr 29 '25 11:04 andrewauclair

Thanks, in this case there is no old layout. I can delete the layout xml to get the error.

tlf30 avatar Apr 29 '25 17:04 tlf30

I think I just reproduced your first stacktrace on 1.1.1 and it's due to some null anchor values in InternalRootDockingPanel dock.
