How to manipulate recursive node with context api?

[Former Member]

Hi, all.

I made a recursive node in my context. So it is like a tree.

When I choosed one child node in my tree, how can I get it`s current element?

Thanks a lot.

Hi, all.

I think that I have to do something in wdDoModifyView method.

The following codes are from the tutorial:

treeNode.mappingOfOnAction().addSourceMapping("path", "selectedElement");

I know that "selectedElement" is the input parameter name of my action method, but I have no idea what is "path"?

Can anyone do me a favor.

Thx.

Hi, Tulasi.

PATH is a constant representing the "path" in the recursive node.

[Former Member]

"path" is the name of the event parameter. You can also use the parameter "nodeElement" instead. The parameter mapping can and should be done at design-time (if available in your release). To do so, right-click the TreeNodeType instance in the Outline view and select "Parameter Mapping". In the dialog you can map event parameters to action parameters using drag-and-drop.

Hi Louis

Sorry for pointing to the wrong link

In Short:you have to add and map the path(of type String) for the event handler

In Sap Help clearly explains about the tree example please look into it.

or

Go to NWDS help Doc just serach for treenodeAPI.You will get complete example to handle this.

Hi, Tulasi.

These are my codes in wdDoModifyView.

if(firstTime)

{

IWDTreeNodeType treenode = (IWDTreeNodeType)view.getElement("TreeNodeType");

treenode.mappingOfOnAction().addSourceMapping("path","select_element");

}

It`s very simple, but I got error when I executed my app.

I thought that I didn`t map the para correctly.

Hi, Armin.

I couldn`t use your way to do Parameter Mapping. When I right clicked my mouse, I didn`t see the option "Parameter Mapping".

My NWDS is 7.0.

Thx for your help.

hi Louis,

selected_element should be of type IWDNodeElement.

Add this parameter to your event handler method.

Hope this helps!

Hi,

Use this code,

if(firstTime)

{

IWDTreeNodeType treenode = (IWDTreeNodeType)view.getElement("TreeNodeType");

treenode.mappingOfOnAction().addSourceMapping("path","select_element");

}
