Question

I developed an application and it works well on OS6 (Operating System 6) but doesn’t work well on OS5 (JDK 5.0). The main problem is that I get data via JSON and displays multiple labels on the screen to show the data but the vertical scroll doesn’t go allow the user to scroll down beyond a certain point. This makes me wonder if the screen in OS5 have limited contents allowed to be drawn on it. snippet code is shown below

JSONArray json = new JSONArray(result);

for (int i = 0; i < json.length(); ++i) 
{
    JSONObject moleculevalue = json.getJSONObject(i);//get the json data object

    String tdescription = moleculevalue.getString("Total Description");


   if (tdescription == "") tdescription = "Not Applicable";              

   _fieldManagerMiddle.add(new SeparatorField());
   _fieldManagerMiddle.add(new LabelField("Description: " + tdescription, Field.FIELD_HCENTER));

}

Data still exist but users cannot scroll below the screen view.

Can anyone tell me a workaround for this and possibly reasons for this. Thanks in advance.

Found solution:
I found out it was a problem with touch devices vs non-touch devices. Hence for non-touch devices, there is a need to set the label control to focusable by

changing

_fieldManagerMiddle.add(new LabelField("Description: " + tdescription, Field.FIELD_HCENTER));

to

_fieldManagerMiddle.add(new LabelField("Description: " + tdescription, Field.FIELD_HCENTER|Field.Focusable));
