Witched Swing JTable!!

[Anonymous]

Hi There:

I hope anyone can give me a hint on this WEIRD behavior (I am really scared!):

Say you have this code somewhere:

TablaAmparos tab (...)
...
Amparo amparo = (Amparo) amparos.get(i); //I am sure this is an "Amparo". No ClassCast...
Object [] dato = new Object[]{amparo.getCodigo(),amparo /*See: I send an "Amparo" for the second column*/ , amparo.getLimites(), amparo.getPorcentajeDeducible()+"%", ((amparo.isTomado())?"S":"N")+((amparo.isObligatorio())?"*":"")};
tab.addRow(dato);

In TablaAmparos.java (Which encapsulates a JTable object to add some functionality):

public void addRow(Object [] data){
model.addRow(data); //See, I don't mess with the data... (Model is a DefaultTableModel)
// this is to have a checkbox in the last column...
String value =  (String) data[data.length-1];
boolean checked = value.indexOf('S')!=-1;
boolean enabled = value.indexOf('*')==-1;
JCheckBox check = new JCheckBox();
check.setSelected(checked);
check.setEnabled(enabled);
checkBoxes.add(check);
}

Now in the same Class:

public List getListaAmparos(){
List resp = new ArrayList();

int numDatos = model.getRowCount(); // Model is the same DefaultTableModel

for(int i=0;i<numDatos;i++){
System.out.println("DATA: "+model.getValueAt(i,1)+" - CLASS: "+model.getValueAt(i,1).getClass());
Amparo amp = null;
try{
// I am sure that I have only "Amparo" classes in the second column (1) in the table:
amp = (Amparo) model.getValueAt(i,1); //El amparo como tal esta en la segunda columna
}catch (ClassCastException e){
System.out.println("Pues este NO es un amparo: "+model.getValueAt(i,1)+" - CLASS: "+model.getValueAt(i,1).getClass());
e.printStackTrace();
}
}
 
}
 

So when I call getListaAmparos() the console should tell me that every row has an "Amparo". Well, surprisingly, it happens exactly that way:


DATA: RESPONSABILIDAD CIVIL CLASS: class co.com.liberty.generales.autos.domain.Amparo
DATA: PERDIDA TOTAL HURTO CLASS: class co.com.liberty.generales.autos.domain.Amparo

Every thing is fine until now, obviously the label appears after the toString overloading in Amparo, but...

Here comes the WEIRD thing...

This table has a TableCellEditor and Renderer that paints a checkbox in the last column and a JComboBox in the
third column of the first row (only the first), to select a value in that cell. Here is the code:

IN:

class EditorCeldasAmparos extends DefaultCellEditor implements TableCellRenderer{
 
...
 
public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {
if(this.columnLimite == column && this.row == row) return limite;
if(this.columnOpc == column) return (JCheckBox) checkBoxes.get(row);
return super.getTableCellEditorComponent(table,value,isSelected,row,column);
}
 
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if(this.columnLimite == column && this.row == row){
valor.setText(limite.getSelectedItem().toString());
return valor;
}
if(this.columnOpc == column) return (JCheckBox) checkBoxes.get(row);
return renderer.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
}

Where limite is the JComboBox...

Well, everything works fine, but, when I select something on the JComboBox or simply step to select any row in the table, the next call to
getListaAmparos() generates this output:


DATA: RESPONSABILIDAD CIVIL CLASS: class co.com.liberty.generales.autos.domain.Amparo
DATA: PERDIDA TOTAL HURTO CLASS: class co.com.liberty.generales.autos.domain.Amparo

Pues este NO es un amparo: ASISTENCIA JURIDICA CIVIL - CLASS: class java.lang.String

at co.com.liberty.generales.autos.webservice.client.gui.VentanaPrincipalPE.getListaAmparos(VentanaPrincipalPE.java:243)
...



Remember how every row has an "Amparo" in the second column??? Well, here it comes Harry Potter and Stringo Patronum!!

I swear that no other code is filling the table and no body else touch the data... So...

What ITH can be happening??

I Hope somebody can do the Mith Busters job and solve this!...

Thanks in advance...

Happy Coding!
