Have some problems by adding children to a tree

[Former Member]

Hello everybody,

i am currently trying to build a tree only with to main branches and each branch has one child. Seems not very difficult, but I think I have a basic problem whose solution i cannot find on my own.

I created a value node "eintraege" awith 3 value attributes "spalte1","spalte2","spalte3". The Recursion node is called "Blubb".Now I am trying this:

  IPrivateTreeView.IEintraegeNode node = wdContext.nodeEintraege();
   IPrivateTreeView.IEintraegeElement newElement = node.createEintraegeElement();
   newElement.setMaster("a");
   newElement.setSpalte1("b");
   newElement.setSpalte2("c");
   newElement.setSpalte3("d");
   wdContext.nodeEintraege().addElement(newElement);
   
   IPrivateTreeView.IEintraegeNode nodeChild = node.nodeBlubb();
   IPrivateTreeView.IEintraegeElement newChildElement = nodeChild.createEintraegeElement();
		newChildElement.setMaster("a");
		newChildElement.setSpalte1("b");
		newChildElement.setSpalte2("c");
		newChildElement.setSpalte3("d");
		
		node.nodeBlubb().addElement(newChildElement);

//Now the second entry

	 newElement = node.createEintraegeElement();
	 newElement.setMaster("a2");
	 newElement.setSpalte1("b2");
	 newElement.setSpalte2("c2");
	 newElement.setSpalte3("d2");
	 wdContext.nodeEintraege().addElement(newElement);
   

		  newChildElement = nodeChild.createEintraegeElement();
		  newChildElement.setMaster("a2");
		  newChildElement.setSpalte1("b2");
		  newChildElement.setSpalte2("c2");
		  newChildElement.setSpalte3("d2");
		
		  node.nodeBlubb().addElement(newChildElement);

But i am just able to oben the frist branch and everythink is working fine, I can see the children as well, but when I am trying to open the second branch nothing happens. What I am doing wrong?

Best wishes

Context:

Entries (node, singleton=false)
-- key (attribute, string)
-- Children (recursion node -> Entries)

IEntriesElement a = wdContext.nodeEntries().createAndAddEntriesElement();
a.setKey("a");
IEntriesElement b = wdContext.nodeEntries().createAndAddEntriesElement();
b.setKey("b");

IEntriesElement a1 = a.nodeChildren().createAndAddEntriesElement();
a1.setKey("a1");
IEntriesElement b1 = b.nodeChildren().createAndAddEntriesElement();
b1.setKey("b1");

Hi thanks for your reply. My problem is know that I am not able to call the method createAndAddEntriesElement(). ("Method is undefined for the Type IEintraegeElement")

What is going wrong?

Hi,

Call the method on the childnode of the element.

From the above example of Armin

Entries (node, singleton=false)

-- key (attribute, string)

-- Children (recursion node -> Entries)

IEntriesElement a = wdContext.nodeEntries().createAndAddEntriesElement();

a.setKey("a");

IEntriesElement b = wdContext.nodeEntries().createAndAddEntriesElement();

b.setKey("b");

IEntriesElement a1 = a.nodeChildren().createAndAddEntriesElement();

a1.setKey("a1");

IEntriesElement b1 = b.nodeChildren().createAndAddEntriesElement();

b1.setKey("b1");

CreateAnd Add is called on a.nodeChildren().

where a is the element of Entries

nodeChildrens is the recursive node name which in tern points ot the entries.

createAndAdd...() is a convenience method (introduced in NW 7.0?) that does the same as

I<Node>Element e = node.create<Node>Element();
node.addElement(e);

If not available, use these 2 statements instead.

Thank you so much now it's working fine.
