My Form class is:
SplashForm
public class SplashForm extends Form {

private Display currentDisplay;
public SplashForm(String title, MIDlet objMidlet,Display objDisplay)
{
//#style splashBackground
super(" " ) ;
this.bookMidlet = objMidlet;
this.currentDisplay = objDisplay;
//#style ticker
this.setTicker("Applicaton Ticker Text" ) ;
}
}
BookingMenuForm
package com.slc.screens;
import com.slc.OctillaMIDlet;
import com.slc.common.MessageConstants;
import javax.microedition.lcdui.List;
import javax.microedition.lcdui.Ticker;
public class BookingMenuForm extends List {
public BookingMenuForm() {
//#style otherBackground
super("", List.IMPLICIT);
//#style bookItemAir
this.append("Air", null);
//#style bookItemHotel
this.append("Hotel"null);
//#style bookItemCar
this.append("Car"null);
//#style ticker
this.setTicker(new Ticker("Application Ticker Text" ) ) ;
}
}
Polish CSS used is:

When I load the .cod file generated from Netbeans IDE I could see the Exception in JDE console
Could not paint the SplashScreenForm,IllegalArgument Exception some 8- 10 times
Could not paint the EventOptionForm, Illegal ArgumentException some 8-10 times
I am not getting the exact linenumber.
Is there any set guidelines to port the application ,designed using j2me polish framework, on Blackberry?
If not, please suggest what is the safest approach to follow ,otherwise, I will end up making a new application for each model using native API. My objective is to port this application on around 250 models.
Thanks
