Water error when accessing Project => Settings => Settings

Elements Water

Update: NEVER MIND! After posting this, and figuring out how to connect to Crossbox from Water, I was able to compile successfully and now this problem has gone away! Hopefully this helps someone else.

Note: Definitely not an emergency, as I am just trying to experiment and learn, so please continue to enjoy your holidays!

I created a new Mercury MacOS project in Water (10.0.0.2587). When I try to access the project’s settings, I get the following error:
Object reference not set to an instance of an object.

Here’s the zip of the project, in case that matters.MacApp.zip (505.0 KB)

Glad to hear; regardless, this should definitely to happen, of course, I’ll have a look.

Thanks, logged as bugs://85370

FWIW, reproduced.

And fixed, though this might be an underlying compiler bug; not sure yet. this code should not NRE, due do boolean short-circuit — but somehow it does…

                    if (crossBox?.IsLocal && crossBox.DoesSupportRosetta2)

Oh good! After I posted the update, it occurred to me you’d probably want to at least update it so that it didn’t cause that error.

Of course, yeah. Already fixed for the next build.
