I have an exception when setting a row sorter to table. I checked it by println it's actually null, but I can't see clearly why. Here is my main class and abstract table model implementation class.

Here is AbstractTableModel implementation
import java.io.Serializable;
import java.util.Vector;
import javax.swing.table.AbstractTableModel;
public class SModel extends AbstractTableModel implements Serializable{
final static String[] headings =new String[] {"Имя","Фамилия",
"Дата приема","Стоимость приема (тыс.сум.)","Врач","Предоплата"};
// final UIManager.LookAndFeelInfo[] info =UIManager
// .getInstalledLookAndFeels();
Vector v;
Vector<Vector<Object>> vv =new Vector<Vector<Object>>();
public void addRow(final Object[] o){
v=new Vector<Object>();
for(final Object element:o){
v.add(element);
}
vv.add(v);
fireTableDataChanged();
}
@Override
public int getColumnCount(){
// TODO Auto-generated method stub
return headings.length;
}
@Override
public String getColumnName(final int column){
return headings[column];
}
@Override
public int getRowCount(){
// TODO Auto-generated method stub
return vv.size();
}
@Override
public Object getValueAt(final int arg0,final int arg1){
return vv.get(arg0).get(arg1);
}
public void removeSelected(final int i){
vv.removeElementAt(i);
}
public void revomeAll(){
vv.removeAllElements();
}
}
And if needed Filer class for writing data or exactly model of table and reading it again
import java.io.BufferedWriter;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class Filer{
File dat;
DataOutputStream doutput;
DataInputStream dinput;
BufferedWriter bwriter;
ObjectOutputStream objout;
FileOutputStream writer;
FileInputStream reader;
ObjectInputStream objin;
public boolean empty =true;
public Filer() throws IOException,ClassNotFoundException{
dat=new File(".//data//data.dat");
if(!dat.exists()){
// System.out.println("here"+dat.getAbsolutePath());
dat.createNewFile();
empty=true;
}else{
empty=false;
}
}
public SModel FilerRead() throws Exception{
reader=new FileInputStream(dat);
objin=new ObjectInputStream(reader);
final SModel n=(SModel)objin.readObject();
objin.close();
return n;
}
public void FilerWrite(final SModel s) throws IOException{
writer=new FileOutputStream(dat,false);
objout=new ObjectOutputStream(writer);
objout.writeObject(s);
objout.close();
}
}
It could be very cool, if would also help with data sort, which user will define through jspinners in top left internal frame. Thank you in advance!

Problem appears when I entering a text to text field and trying to sort table by clicking button. Here is that stroke:
public static void filter(){
table_1.setRowSorter(sorter);//It is here. table_1 equals null but I can't see why.
final String text=search.getText();
if(text.length()==0){
sorter.setRowFilter(null);
}else{
try{
sorter.setRowFilter(RowFilter.regexFilter(text));
}catch(final PatternSyntaxException pse){
System.err.println("Bad regex pattern");
}
}
}
Oh, thanks I see now. I just rediclared it in main.
