Hi,
With Toffeev1 set to no, after an exceptions is raised the locals window stops working.
I have a breakpoint set on the raise
e
It also has the same problem if I move the raise outside the constructor
method application(application: UIApplication) didFinishLaunchingWithOptions(launchOptions: NSDictionary): Boolean;
begin
window := new UIWindow();
window.rootViewController := new UINavigationController withRootViewController(new ViewController);
// Custom initialization
raise new ArgumentNullException;
window.makeKeyAndVisible;
result := true;
So Im thinking its maybe 2 issues
Cheers,
John
Can i get the full exception info? it should show in the Activity window.
This looks like its for the watch window

Do I just need to download a new zip distro or would it require a new fire build ?
New Fire.
I get this now

The locals window looks ok
Would this be an unrelated issue? what are the steps to reproduce?
sorry I think this is my mistake because I cant reproduce the InvalidCastException.
If I run the sample I attached in the first post. I get the original error. The locals window is now fixed but should it be showing me an AgumentNullException or a NullReferenceException ?
From the callstack it looks like the ArgumentException ctor raises an NRE… I’ll check the code. Is this Island or Toffee?
Reproduced. curiously for Island, but not ToffeeV1, even tough this toffee code looks fishy, with the result :=…
constructor(aMessage: String);
begin
{$IF TOFFEE}
result := inherited constructor withName('Exception') reason(aMessage) userInfo(nil);
{$ELSE}
inherited constructor(aMessage);
{$ENDIF}
end;
Fixed, i think (blind/untested). TOFFEE of course builds for ToffeeV2, but it seems “result :=” is fine in Toffee (though wrong) but not in Island. The NRE happened in Toffeev2 only.
I’ll log to see of the compiler should fail on result := in the ctor.
I guess I need to build from source to try this ?
Yes, or get next build
I tested with today build, it didnt seem to make a difference. Did you manage to fix the community license for rtl2 ? I wanted to debug against that on my local
You mean the NRE inside ArgumentNullException? Strange. FWIW, the change was merged, but ofc it could be that the issue was something else; I didn’t get a chance to retest yet, myself.
Not yet, will check now
