on a compiled app, one of my customer gets this error sometimes. I’ve never seen it in a debug app.
what can it come from ?
thanks.
this error is inside a compiled xojo app I made, this part is certainly inside the xojo framework, which I have no access at all ! only people from xojo team or people making xojo plugins may have an answer to my question …
My apps have no plugin except the postgres and mysql database.

Then you will see that you will be able to solve the problem. Good luck and sorry for the inconvenience
This looks like a failed assertion in the Xojo framework. The variable imp is nil.
That usually means the implementation c++ object was not created or freed too early.

It can happen when App is compiled for older macOS and run in recent one.
With which Xojo version was this compiled?
My guess… compiled with an older Xojo version and your customer runs the latest macOS version. Seen that before.
compiled with xojo 2024r31, and customer is on sonoma or sequoia I don’t recall. I will soon deliver an update with xojo 2024r41, will see
did you get this exact same error message yourself ?
What version of macOS?
I don’t recall but the customer has a recent macbook. so sonoma or sequoia.
So it could be that you’re using a feature that no longer exists in the SDK. Could you give a list of the items in your toolbar including the non-button items?
I’m pretty sure that Apple deprecated separators a while ago, but I’d expect you to get that assertion immediately every time if it was totally gone.

I’m just thinking that this separator does nothing here …
will try to remove it and see how it goes.
thanks Greg.
Just don’t understand why more than 10 users have this app, and only one gets the error from time to time !
all users have recent mac and systems.
You would need more data. It’s possible that the affected system has a text encoding that you didn’t plan for or right to left text or something odd like that.
Oh hey, do you add and remove items from this toolbar at runtime?
no I just hide or display some .
Aha! So… in the macOS SDK, there’s no such thing as a hidden toolbar item. Under the hood, the items are physically removed from the list of items on the bar when you hide them and then added back onto that list when you make them visible.
So it could be that these users are getting caught in the limbo somehow between taking an action and the item being hidden/removed. The item being removed might cause the equivalent of a nilobjectexception in the Xojo framework if it was then accessed by another part of the framework.
I don’t understand why because I hide/show them at the opening of the window
there are no dynamic hide/show during the user time.
more information, sometimes the customer gets a macos error. here is the dump.
