I am new with Primefaces and I try to use a treeTable from Primefaces 3.3.1.
Only the first record of the TreeTable is shown at the beginning. Then, when I click on the little image to expand the TreeTable, nothing happens. In FireBug, I can se the following result:
<partial-response>
<error>
<error-name>class java.lang.StringIndexOutOfBoundException</error-name>
<error-message>String index out of range: -1</error-message>
</error>
</partial-response>
If I force my treeTable to be expanded with node0.setExpanded(true), then the TreeTable is expanded. Then I can collapse it but again, I am no more able to expand it.
In other posts, it is written that the model and/or the bean must implements Serializable. I try but it does not work.
Below, my model (what will be placed in each record of the TreeTable):
public class MyModel{
private String field_1;
private String field_2;
public MyModel(){};
public MyModel(String field_1, String field_2){
this.field_1 = field_1;
this.field_2 = field_2;
}
//Getters and setters
}
Below, the JSF Managed bean that create the TreeTable:
@ManagedBean
@SessionScoped
public class MyManagedBean{
public TreeNode root;
}
public MyManagedBean{
root = new DefaultTreeNode("root",null);
TreeNode node0 = new DefaultTreeNode(new MyModel("Field 1", "Field 2"), root);
TreeNode sub0 = new DefaultTreeNode(new MyModel("Sub", "Sub"), node0);
//node0.setExpanded(true);
}
public TreeNode getRoot(){
return root;
}
Finally, my JSF file:

</f:facet>
<h:outputText value="#{test.field_2}" />
</p:column>
</p:treeTable>

Thank you in advance for your help!
Solved it. I forgot to wrap the treeTable in an h:form tag. It works fine now.
