我正在尝试学习 PF,所以我首先显示数据表并导航到 rowClick 传递参数的下一页,但遇到以下错误。我发现这个问题有类似的问题,但还没有运气。我希望有人能帮助我。
我收到以下错误:
DataModel must implement org.primefaces.model.SelectableDataModel when selection is enabled.
Caused by:
javax.faces.FacesException - DataModel must implement org.primefaces.model.SelectableDataModel when selection is enabled.

}

其他豆类:
public class Car{

private String randomColor;
public String getRandomColor() {
return randomColor;
}
public void setRandomColor(String pRandomColor) {
randomColor = pRandomColor;
}
public String getModel() {

public void setModel(String pModel) {
model = pModel;
