Crash on iOS after editing a TextArea

[Arne Sikström]

I have two TextAreas in a Form. If I start to edit the first one and the press "Next", everything is fine, but when I press "Done" on the last one I get a NPE. This works on the simulator and also worked a couple of days ago on the device.

The log in Xcode is not very helful:

I have even removed all hand made code in that Form(Main) but I still get a crash.

I am quickly running out of trouble shooting options here, any ideas?

[Arne Sikström]

I made a simple test case for this. Is this a regression for r1665 or r1666?

package userclasses;

import com.codename1.io.Log;

import com.codename1.ui.Button;

import com.codename1.ui.Container;

import com.codename1.ui.Form;

import com.codename1.ui.Label;

import com.codename1.ui.TextArea;

import com.codename1.ui.events.ActionEvent;

import com.codename1.ui.events.ActionListener;

import com.codename1.ui.layouts.BorderLayout;

import com.codename1.ui.layouts.BoxLayout;

public class MyApp {

private int numb = 0;

public MyApp() {

}

public void start() {

Log.p("start in Myapp");

Form main = new Form("Test of TextArea");

TextArea firstArea = new TextArea(3, 20);

TextArea secondArea = new TextArea(3, 20);

final Label label = new Label("Some text");

Button actionButton = new Button("The action starts here");

actionButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent evt) {

numb++;

label.setText("Pressed: " + numb);

}

});

main.setLayout(new BorderLayout());

Container center = new Container(new BoxLayout(BoxLayout.Y_AXIS));

center.addComponent(firstArea);

center.addComponent(secondArea);

center.addComponent(label);

center.addComponent(actionButton);

main.addComponent(BorderLayout.CENTER, center);

main.show();

}

}

Thanks, this was fixed in the server 90 minutes ago or so.

[Arne Sikström]

Now it works, Thanks.
