[ULC-developer] private ULC visual class and coder

[Mario H. Castillo]

Hi Janak,

I have the following class and corresponding coder and hopefully you might 
have some clues for me:

public class Data {

 private ULCCheckBox checkBox;

 public Data() {
   checkBox = new ULCCheckBox();
   checkBox.setOpaque(true);
 }

 public void setValue(Object value) {
   if (value == null)
     checkBox.setSelected(false);  // Gibts hier kein State??
   else
     checkBox.setSelected(((Boolean) value).booleanValue());
 }

   public Object getValue() {
       return checkBox.isSelected();
   }
}

CODER

public class DataCoder implements IStreamCoder {

   public String getPeerClassName() {
       return Data.class.getName();
   }

   public void writeObject(IObjectOutputStream out, Object data) {
       Data c = (Data) data;
       try {
           out.writeObject(c.getValue());
       } catch (IOException e) {
           e.printStackTrace();          }

   }

   public Object readObject(IObjectInputStream in) throws IOException {
       Object o= (Object)in.readObject();

       Data p= new Data();  <+++++++++++++++++++ Executes here and gives 
exception!!!!!
       p.setValue(o);
       return p;
   }
}

Is the ClientContext null??? Or is it something else you think?

Mario
