Node inside Node

[Former Member]

Hi,

I am facing a problem in getting and setting the node from webservice node. I have two nodes of the following structure.

<i>MainNode</i> (Model node)

-

---

<i>SubNode</i> (Model node under MainNode)

-

---

<i>ItemNo</i> (Attribute under SubNode)

-

---

<i>lotNo</i> (Attribute under MainNode)

-

---

<i>quantity </i> (Attribute under MainNode)

Now I have a table which has 3 columns. 2 are lotNo and quantity whose values are retrieved from MainNode. The third column is a button on click of which I get a popup displaying a table of ItemNo from SubNode. For each lotNO, I should get different sets of ItemNo values. I am confused on how to get values for ItemNo. Whichever row's ItemNo button I click on, I get same set of ItemNo for different lotNo also. Kindly guide me the correct way to get the ItemNo from the structure above ( How to set vaues from node inside node).

Hi Harini,

You can get an idea by looking this tutorial:

Hi,

We worked with workaround with having the variables directlt under main node instead of having them inside another node.

Hi Harini,

If you are using NW04S or NW04 >=SP13 , you can set the Table property "CompatibilityMode" to "NW04Plus", which will solve your problem.

Hai Harini,

u dont need child element, if leadsection was set then automatically child SubNode leadselection also changes.

wdcontext.nodeMainNode().setLeadSelection(row);

// row is an integer value, which represent the on which row( or node element) selected in the MainNode

int size=wdcontext.nodeSubNode().size;

for(int i=0;i<size;i++){

retrieve all the ItemNo here

// String itemNo=wdcontext.nodeSubNode().getSubNodeElementAt(i).getItemNo()

// like this u will the different ItemNos

}

Hi,

Both the nodes are model nodes with singleton = true. So I can't get the result as u all suggest. Kindly let me know some other solution.

Hai Harini,

To get the diffirent ItemNos on clicking on the different button of the different row, set the leadselection of the MainNode to the row in which button was selected then u will get the ItemNos of that SubNode.

u said that u r getting the Same ItemNos by clicking on the button of the different row, this happens because of the leadselection of the MainNode, leadselection remains same( Zero ) when u r retrieving ItemNos, that y u r receiving ItemNOs of the first MainNode node

Hi siva,

Lead Selection is fine. But how do I get the child element? Can u send some sample piece of working code? That would be greatly helpful. Thanks.

Hi Harini,

Instead of taking the third column take only two columns and

after selecting any row navigate to the view in which you want to show

the child details.

for filling the Node_Item, you have to use Supply function property of the node.

where you have to provide a function name which fills the child node data.

Hi,

When the web service model has executed, I'll get all the values of the nodes. Now I've to access and get the values from the nodes. How do I loop from the values in the MainNode and SubNode to find out that a particular vaue of a subnode element belongs to the MainNode?

Hi Harini,

Get the Main Node Element from the Lead Selection

int i = wdContext.nodeHeader().getLeadSelection();

headerElement = wdContext.nodeHeader().getElementAt(i);

int size = mainNodeElement.node<childNode>.size();

for( i=0; i<size; i++)

childnodeElement = mainNodeElement.node<childNode>.getElementAt(i);

and retrieve values from the childnodeElement.

Hi Abhimanyu,

I am not able to get the node<childNode> itself from the parent element.

<b>mainNodeElement.node<childNode>.getElementAt(i);</b>

Kindly help me.

Hi Harini

check the singleton property of the child node if it is true then you cannot

see that method, cause you have only one instance of that node.

if it is false you have only one instance of item level node, you can get it

directly using

wdContext.current<ChildNode>.getAttributes();
