ScrollableDataModelRowKeyConverter

[eugenbesel]

hello,

I have Richfaces 3.3.2 CR1

I try to implement ScrollableDataModel using attribute columns.

I have a question about currentPK. This object is used in each Model in methods

1. private Integer currentPk; 
2. @Override 
3. public Object getRowKey() 
4. {
5.     return currentPk; 
6. }
8. @Override 
9. public void setRowKey(Object key) 
10. {
11.     this.currentPk = (Integer) key; 
12. }

My question is, which value can be this object? in this example it is just an object.

I get an ConverterException with message:

Value 4 is not supported by this converter.

or if I use String

Value michael is not supported by this converter

ScrollableDataTableRowKeyConverter.getAsString.

My currentPK is a String from the first column I have.

this exception occurs when the line

visitor.process(context,row.get(1),argument) in the methods walk (FacesContext context, DataVisitor visitor, Object argument) called

Integer or SimpleRowKey are handled by this converter.
