Blackberry ObjectChoiceField Not Showing drop down list - blackberry

Question

ObjectChoiceField not working because the below code:
protected boolean navigationUnclick(int status, int time) {
return true;
}
I have added this code to remove the menus on touchevent. Means I have made a custom bottom tab and adding and deleting verticalfields on screen. When i touch any HorizontalField it shows menu that's why i added the above code.
This is my code contains ObjectChoiceField added in horizontalfield:

GetUserListIntermediator getUserListIntermediator=new GetUserListIntermediator(ageRange,gender,religion);
PleaseWaitPopupScreen.showScreenAndWait(getUserListIntermediator, Constant.PLEASE_WAIT_TEXT);
}
}
}
could anyone answer me how to solve this problem.

Answer 1

You don't get drop-down list because the field code does not process unclick event. You have intercepted and consumed this event (via return true;) before your field can process it.
Try this code for your event handler.
protected boolean navigationUnclick(int status, int time) {
super.navigationUnclick(status, time);
return true;
}
