Tree - create tree item

[Former Member]

Hello,

have the following Context Node:

IncidentHeader

--descript

--event

--type

Collection Cardinality of IncidentHeader is 1..1. How can I create in the Outline-View a tree exacly like the Context Node. I tried it like this:

Tree (dataSource: IncidentHeader)

--TreeNode (dataSource: IncidentHeader)

--TreeItem1(dataSource: IncidentHeader, text: IncidentHeader.descript)

--TreeItem2(dataSource: IncidentHeader, text: IncidentHeader.event)

--TreeItem3(dataSource: IncidentHeader, text: IncidentHeader.type)

But it shows only one node with the text of the TreeItem3.

Hi,

Change the cardinality of node IncidentHeader to 0..n

thanks & regards,

Hi Manoj,

I have to change IncidentHeader cardinality to 1..n because I initialize it in wdDoInit().

If I do that the the View shows:

-IncidentHeader/@type

-IncidentHeader/@type

-IncidentHeader/@type

And the browser shows one node with the text of the text of IncidentHeader.type.

Hi,

That' fine. What is the problem now.

Is it not showing you all the elements of the node IncidentHeader in your tree?

thanks & regards,

Hi Manoj,

yes it's only showing the treen node type.

I think you misunderstood the data binding model for the tree. The TreeNodeType and TreeItemType view elements do not represent single tree nodes in the rendered tree but they are templates for the different types of tree nodes that result from the context elements.

Ok.

But how can I do just a single tree node like this:

IncidentHeader

--descript

--event

--type ?

Do you really need a tree for this?

You could use a recursive context structure like

TreeNode (node, 0:N)

- text (string)

- Children (recursion node -> TreeNode)

with 4 node elements v0, v0.Children.0, v0.Children.1, v0.Children.2

v0.text = "IncidentHeader"

v0.Children.0.text = <description>

v0.Children.1.text = <event>

v0.Children.2.text = <type>

and data binding

Tree.dataSource = TreeNode

TreeNodeType.dataSource = TreeNode

TreeNodeType.text = TreeNode.text

But I doubt that's what you want

I just want to represent my Context Node

IncidentHeader

--descript

--event

--type

in a tree like this:

Initial Inidident data

--descript

--event

--type

Yes I know, but it is not possible directly.

Hello Armin,

I don't know what you exactly mean with that.

How can create a "recursion node -> TreeNode"?

And how can I bind Tree.dataSource to a TreeNode?

Can you explain me exactly what I have to do?

In the context editor: New -> Recursion Node...

and in the recursive child reference the parent node (named "TreeNode" in my example)

Tree.dataSource = TreeNode means: bind property "dataSource" of Tree UI element named "Tree" to context node named "TreeNode".

If the cardinality is 1:1 there exists only one element in that node. Then what should the tree display?

Hi Armin,

the cardinality is 1:1 of Node Incident Header. And it shows only the text of TreeNode3.
