How about something like this:
public class CommaSeparatedToStringListModel implements IModel<List<String>>
{
private final IModel<String> csvModel;
public CommaSeparatedToStringListModel(final IModel<String> csvModel)
{
this.csvModel = csvModel;
}
public List<String> getObject()
{
return new
ArrayList<String>(Arrays.asList(csvModel.getObject().split(",")));
}
public void setObject(final List<String> strings)
{
StringBuilder builder = new StringBuilder();
for (String string : strings)
{
if(builder.length() > 0)
{
builder.append(",");
}
builder.append(string);
}
csvModel.setObject(builder.toString());
}
public void detach()
{
csvModel.detach();
}
}
