Hi,
Naively I followed the instructions on building a tree i.e. sth. like
* Example: Given the following class:
* <pre>
* public class Person
* {
* public Person(String name)
* {
* _name = name;
* }
*
* public String getName()
* {
* return _name;
* }
*
* public List getKids()
* {
* return _kids;
* }
*
* private final String _name;
* private final List _kids = new ArrayList();
* }
* </pre>
* You can construct a tree by:
* <pre>
* Person john = new Person("John Smith");
* Person kim = new Person("Kim Smith");
* Person tom = new Person("Tom Smith");
* Person ira = new Person("Ira Wickrememsinghe");
* Person mallika = new Person("Mallika Wickremesinghe");
*
* john.getKids().add(kim);
* john.getKids().add(tom);
* ira.getKids().add(mallika);
*
* // create the list of root nodes:
* List people = new ArrayList();
* people.add(john);
* people.add(ira);
* </pre>
* Now you can construct a TreeModel by:
* <pre>
* TreeModel model = new ChildPropertyTreeModel(people, "kids");
Now I would like to open a node programmatically on the Java side. However,
when I use the isContainer method before enterContainer I get an
IllegalArgument exception while trying to call
javax.faces.model.ScalarDataModel.getRowData.
Is there another way to open a certain node? Would I use rowKeys?
Regarding the rowKey approach, I have the impression that the rowKey
approach does not seem to be really feasible; as far as I can see in the
debugger, I could only verify one rowKey instance for the root node but I
did not find any other rowKey object for other existing nodes..
Do I need to use the Menu variation of the tree classes for rowKeys to
work?
Further details:
I use a Pojo MenuItem that has a children property which is an
ArrayList<MenuItem>.
I use SEAM 2.0 RC1.
I apply the org.apache.myfaces.trinidad.model.ChildPropertyTreeModel
implementation of org.apache.myfaces.trinidad.model.TreeModel.
Many thanks,Wolfgang.
