Do you have an animation in progress or are you changing the UI from a separate thread?

No i dont think so, its happening on ios and simulator though. it would be very handy if the stacktrace it threw pointed to a line in my code but it doesnt :-(

That generally means the layout code here failed:

        layout.layoutContainer(this);
        int count = getComponentCount();
        for (int i = 0; i < count; i++) {
            Component c = getComponentAt(i);
            if (c instanceof Container) {
                ((Container) c).layoutContainer();
            }else{
                c.laidOut();
            }
        }
        laidOut();
        onParentPositionChange();

Do you see any reason why count will be 2 and then while iterating the components will no longer be there?
If you can reproduce this in the simulator I suggest starting from there.

i am actually removing the 3 main containers from the main form just before this happens, but i dont understand why that would crash it still, when theyre removed, then cn1 should know theyve been removed and the count will drop'?

Here is the code i call not long before the crash, this isnt in call serially because then i was getting a flash of the form before it blacks out. The purpose of this method is just to be able to turn a form into a black screen when things need to happen automatically and without seeing the screen come up.

private void blackOutForm(final Form f, String whoCalled)

{

_("blackOutForm start... whoCalled->"+whoCalled);

//this needs to fully finish a frame before we proceed

// Display.getInstance().callSerially(new Runnable() {

// public void run() {

_("a");

if (f.getUIID().equals("BLACK"))

{

_("form already blacked out no need to do it again.");

return;

}

f.setUIID("BLACK");//make it an empty black form. //keep this out here

_("b");

//remove topbar and center

Container TOPBAR = (Container) nl.t.findByNameX("TOPBAR_NORTH", f );

if (TOPBAR!=null)

{

_("x1");

f.removeComponent(TOPBAR);

}

Container CENTER = (Container) nl.t.findByNameX("CENTER", f );

if (CENTER!=null)

{

_("x2");

f.removeComponent(CENTER);

}

Container SOUTH = (Container) nl.t.findByNameX("SOUTH", f );

if (SOUTH!=null)

{

_("x3");

f.removeComponent(SOUTH);

}

_("c");

f.invalidate();

_("d");

_("blackOutForm end");

// }

// });

}

If you still have a transition or animation going this will happen since references might still exist to these components.
callSerially will postpone to the next EDT cycle not till the animations are finished. I'll need to understand what sort of animations you have going (transition, hierarchy etc.) to give you better advice.

Im not using anything like that, its all default stuff, the only thing I can think of is I have formTransitionOut set to Slide and includeNativeBool = true

I was just thinking, you know if you wish to remove something from a form, should that be done in POST or PRE? Im doing all my funky stuff in postShow, if I do it in preshow maybe my problems will go away ?
