One of the scenario I found that When both soft keys gets hanged and if we keep phone idle, after sometime application will able to take events from the soft key buttons.

Is that memory related issue or something else..

Please help me its urgent...

Hi All,
When I pressed OK key (Center Key) to open choicegroup list items and select something and goes back to the form that has choicegroup., left and right soft keys get hanged and no event occurs on pressing these any of the soft key.

Were there any exceprtion/errors displayed by device?
Did any other key workd except the two you mentioned?
have you added commands on the LSK and RSK and are not working while you are coming back to the form?

thanks for the reply...

No exceptions were thrown by the device , just LSK and RSK gets hanged after coming back to the form from choicgroup POPUP list.

All other keys were working fine.

I have added buttons. My J2me code is....

public class TestMidlet extends MIDlet implements CommandListener{

	private Form form;
	
	private StringItem str_test;
	private TextField tf1;
	private TextField tf2;
	private ChoiceGroup ch1;
	
	private Command cmd_Ok;
	private Command cmd_Exit;
	
	private String[] arr_Relation = {"Father","Mother","Brother","Sister"
										,"Wife","Husband","Uncle","Cousin"
										,"Father-in-law", "Mother-in-law"
										,"Brother-in-law","Sister-in-law"
										,"Grandfather","Grandmother"
										,"Grandson","Granddaughter"};
	
	private boolean isPaused= false;
	
	
	public TestMidlet() {
		// TODO Auto-generated constructor stub
		//midletInstance = this;
	}

	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
		// TODO Auto-generated method stub
		System.out.println("In destroy app");
	}

	protected void pauseApp() {
		// TODO Auto-generated method stub
		System.out.println("In pause app");
		isPaused = true;
	}

	protected void startApp() throws MIDletStateChangeException {
		// TODO Auto-generated method stub
		System.out.println("In start app");
		
		if(!isPaused){
		
			Display display = Display.getDisplay(this);
			
			form = new Form ("Test Form");
			
			str_test = new StringItem("Hello World","Hello J2ME",StringItem.PLAIN);
			
			tf1 =  new TextField("Textfield 1","",20,TextField.ANY);
			tf2 =  new TextField("Textfield 2","",20,TextField.ANY);
			
			ch1 = new ChoiceGroup("Choicegroup 1",ChoiceGroup.POPUP,arr_Relation,null);
			
		    // append form items
			form.append(str_test);
			form.append(tf1);
			form.append(tf2);
			form.append(ch1);
			
			cmd_Exit = new Command("Exit",Command.EXIT,0);
			cmd_Ok = new Command("OK",Command.OK,0);
			
			// add commands
			form.addCommand(cmd_Ok);
			form.addCommand(cmd_Exit);
			form.setCommandListener(this);
			
			// display form
			display.setCurrent(form);
		
		}else{
			System.out.println("midlet resumed");
		}
	}

	public void commandAction(Command arg0, Displayable arg1) {
		// TODO Auto-generated method stub
		if(arg0.getLabel().equals("Exit")){
			notifyDestroyed();
		}else if( arg0 == cmd_Ok){
			form.append("Ok called");
		}
	}
}

As mentioned in my earlier post that it was found with combination of textfield and choicegroup on same form , If I didnt append textfields then LSK and RSK not get hanged after coming from choicegropu popup list to form.

What is the reason behind this?

Thanks All....

Hi r2j7,

I also having the same issue.

Is there any work around or minor fix we can apply.

Thanks,

Hello hellfire001ph,

As an additional info, I checked further and it is also on Nokia X2-01 (a full QWERTY device like C3-00).

Since the issue is related to the UI component itself then the only solution for the affected devices would be not to use it..

Have you checked if you could use an Exclusive List instead?:

List list = new List("Choices", Choice.EXCLUSIVE);

Hi r2j7,

Yup Exclusive is working but this will display all the content which is about 20-50 items. hmm may be i need to create a sub form for this while waiting for the fix.


Thanks,

Hello hellfire001ph,

just to get back to you on this, unfortunately there will not be a software fix to the ChoiceGroup issue on Nokia C3-00 and Nokia X2-01. Therefore it is recommended to find a custom solution to the issue.

I will create a Known Issue article to Nokia Developer Wiki on the issue.
