That's what I did. But something is wrong, because the error
"[ServletException in:/eservices/layout/layout.jsp] null' " appears.
public DataModel getFieldsEmbque() {
if(fieldsEmbqueModel == null) {
fieldsEmbqueModel = new ArrayDataModel(fieldsEmbque);
}
return fieldsEmbqueModel;
}
public List getValuesEmbque() {
if(valuesEmbque == null) {
valuesEmbque = new ArrayList();
valuesEmbque.add(new RowData(this, fieldsEmbque));
valuesEmbque.add(new RowData(this, fieldsEmbque1));
}
return valuesEmbque;
}
public class RowData
{
private RemessaBean fieldHolder;
private Fields[] fields;
public RowData(RemessaBean fieldHolder, Fields[] fields)
{
this.fieldHolder = fieldHolder;
this.fields = fields;
}
public Object getValue()
{
System.out.println(((Fields)this.fieldHolder.getFieldsEmbque().getRowData()).getValue());
return fields;
}
}
Help me please!!!!
Thanks.
