I use the AbstractVisionComponent  
I’m looking for the synthax to add “dataset” prop in the CommonBeanInfo ?  
and the java type for the associed getter and setter for the dataset ?

You’re example is fine for a text prop :

addProp(“text”, “Text”, “The text to display in the component”, CAT\_DATA, PREFFERED\_MASK | BOUND\_MASK);

public String getText() {  
return text;  
}

public void setText(String text) {  
// Firing property changes like this is required for any property that has the BOUND\_MASK set on it.  
// (See this component’s BeanInfo class)  
String old = this.text;  
this.text = text;  
firePropertyChange(“text”, old, text);

repaint();  
}

In the bean info class you do the following:`addBoundProp("data", "Data", "The data for this component", CAT_DATA, PREFERRED_MASK);`In your Java class you do the following:[code]public Dataset getData() {  
return data;  
}

public void setData(Dataset newDataset) {  
if (newDataset == null) {  
newDataset = new BasicDataset(new ArrayList(0), new ArrayList\<Class\<?\>\>(0), new Object[][] {});  
}

```
Dataset oldDataset = this.data;
this.data = newDataset;

// Do something with the data like update component

firePropertyChange("data", oldDataset == newDataset ? null : oldDataset, newDataset);

```

}[/code]
