Picker not showing at the right moment - codenameone

Question

I am experiencing some weird behavior with the pickers in my app since the pixel perfect picker update : The picker is showing when the form is called to be show, so before the form is showing.
I've tried with the new lightweight mode, with the old mode, inside a PickerComponent, with just a picker, on Android 7, iOS 10 and the simulator, all have a similar behavior.
The only difference is that with a PickerComponent, the bug appear when the Form is shown a second time.
The bug occur once, because I keep my forms in memory most of the time and it occur only the first time.
Here is a little code sample to add in the start method of the barebone hello world :
Picker pick = new Picker();
pick.setType(PICKER_TYPE_STRINGS);
pick.setStrings("First model", "Second model", "Third model");
pick.addActionListener(e->Dialog.show("Picker result", pick.getSelectedString(), "OK", null));
pick.setUseLightweightPopup(false);
Picker pick2 = new Picker();
pick2.setType(PICKER_TYPE_STRINGS);
pick2.setStrings("First model", "Second model", "Third model");
pick2.addActionListener(e->Dialog.show("Picker result", pick2.getSelectedString(), "OK", null));
pick2.setUseLightweightPopup(true);
PickerComponent pickerComponent = PickerComponent.createStrings("First model", "Second model", "Third model").label("Model Heavy");
pickerComponent.getPicker().setUseLightweightPopup(false);
pickerComponent.getPicker().addActionListener(e->Dialog.show("Picker result", pickerComponent.getPicker().getSelectedString(), "OK", null));
PickerComponent pickerComponent2 = PickerComponent.createStrings("First model", "Second model", "Third model").label("Model Light");
pickerComponent2.getPicker().setUseLightweightPopup(true);
pickerComponent2.getPicker().addActionListener(e->Dialog.show("Picker result", pickerComponent2.getPicker().getSelectedString(), "OK", null));
Form hi = new Form("PickerCompo Heavy", BoxLayout.y());
hi.add(pickerComponent);
Form hi2 = new Form("PickerCompo Light", BoxLayout.y());
hi2.add(pickerComponent2);
Form hi3 = new Form("Picker Heavy", BoxLayout.y());
hi3.add(pick);
Form hi4 = new Form("Picker Light", BoxLayout.y());
hi4.add(pick2);
Form caller = new Form("Call Hi World", BoxLayout.y());
Button callForm = new Button("hit me heavyweight Compo");
callForm.addActionListener(e->{
hi.setBackCommand("Back", null, ev-> caller.showBack());
hi.show();
});
Button callFormLight = new Button("hit me Lightweight Compo");
callFormLight.addActionListener(e->{
hi2.setBackCommand("Back", null, ev-> caller.showBack());
hi2.show();
});
Button callForm3 = new Button("hit me heavyweight");
callForm3.addActionListener(e->{
hi3.setBackCommand("Back", null, ev-> caller.showBack());
hi3.show();
});
Button callForm4 = new Button("hit me Lightweight");
callForm4.addActionListener(e->{
hi4.setBackCommand("Back", null, ev-> caller.showBack());
hi4.show();
});
caller.add(callForm);
caller.add(callFormLight);
caller.add(callForm3);
caller.add(callForm4);
caller.show();
Any idea of a workaround ? I'm using them on some major forms in my app, and I'd like to update the app to resolve the distorting screen on iOS (SO : Distorted screen ).

Answer 1

There was a regression with Picker due to changes in the focus functionality that were used with the Picker change but are applicable even in the native functionality.
This should be fixed in the update that we pushed out just now.
