    RF 4: Example of using org.richfaces.model.TreeDataModel?

    codo Newbie

      Hello,

       

      I am trying to implement the new org.richfaces.model.TreeDataModel interface to manipulate tree data. I have no success in doing that. I understand that my implementation class has to extend org.ajax4jsf.model.ExtendedDataModel to work properly. I overrode all methods that I'm supposed to override. The result of my attempts are properly rendered tree, but when I try to expand a node exceptions are thrown. I'll be greatfull if someone give me an example how to use this new model properly.

       

      Greetings

            Hello,

             

            Sorry for my late response. I'll show you part of my code.

             

            My model implementation:

             

            public class MyRFTreeDataModel extends ExtendedDataModel<Picture>

                    implements TreeDataModel<Picture>, Serializable {

             

                private Picture data;

                private Object rowKey;

                private List<TreeDataModelTuple> children = new ArrayList<TreeDataModelTuple>();

                private MyRFTreeDataModel parent;

             

                public MyRFTreeDataModel() {

                    this.data = new Picture("Root", null);

                }

             

                public MyRFTreeDataModel(Object rowKey, Picture data) {

                    this.rowKey = rowKey;

                    this.data = data;

                }

             

                @Override

                public Object getRowKey() {

                    return rowKey;

                }

             

                @Override

                public void setRowKey(Object o) {

                    this.rowKey = o;

                }

             

                @Override

                public boolean isDataAvailable() {

                    if (data != null) {

                        return true;

                    }

                    return false;

                }

             

                @Override

                @Override

                    return data;

                }

             

                @Override

                public Iterator<TreeDataModelTuple> children() {

                    return children.iterator();

                }

             

                @Override
