Hello!
As in example I've inserted in context a special recursive Child node and then assigned parent node to this node's "repeated node" property. Parent node is mapped to the following JavaBean:
public class TreeNode {
/**
*/
Integer id;
Integer parentId;
String name;
Boolean hasChildren;
public TreeNode() {
super();
// TODO Auto-generated constructor stub
}
/**
*/
public Integer getParentId() {
return parentId;
}
/**
*/
public void setParentId(Integer parentId) {
this.parentId = parentId;
}
/**
*/
public Integer getId() {
return id;
}
/**
*/
public void setId(Integer id) {
this.id = id;
}
/**
*/
public String getName() {
return name;
}
/**
*/
public void setName(String name) {
this.name = name;
}
/**
*/
public Boolean getHasChildren() {
return hasChildren;
}
/**
*/
public void setHasChildren(Boolean hasChildren) {
this.hasChildren = hasChildren;
}
public List getTreeNodes() {
ModelClass model = new ModelClass();
return (List) model.getTreeNodes();
}
public List getRootNodes() {
ModelClass model = new ModelClass();
return (List) model.getRootNodes();
}
public List getChildNodes() {
ModelClass model = new ModelClass();
return (List) model.getChildNodes(getParentId());
}
public static void main(String args[]) {
ModelClass model = new ModelClass();
model.getTreeNodes();
}
}
When I'm trying to deploy and run application I get the following exception:
"com.sap.tc.webdynpro.progmodel.context.ContextException: RecursiveNodeInfo(MainView.TreeNode.Child): you cannot add a recursive child to a mapped node mapped to a data node without recursion"
Can anybody help?
