Dynamic binding attributes to inputfields

[Former Member]

Hello,

Im trying to fill an UI dynamically. I've created a layout with mostly Inputfields with propert id'sn. Now i try in the wdDoModifyView to create a node with appropriate attributes to fill the inputfields. Im doing:

if(firstTime)
    {
	//create an APNode under which all the ap specific fields are gonna be created
	IWDNodeInfo nodeInfo = wdContext.getNodeInfo().addChild("APNode",null,true,true,false,false,false,true,null,null,null);
	//create a attribute invoice under apNode
	IWDAttributeInfo info = wdContext.getChildNode("APNode",IWDNode.LEAD_SELECTION).getNodeInfo().addAttribute("invoice","ddic:com.sap.dictionary.string");
	//get the field and bind it to the attribute just created
	IWDInputField field = (IWDInputField)view.getElement("invoiceInputField");
	field.bindValue(info);
	//fill the attribute with mock data
	IWDNodeElement dynEle = wdContext.getChildNode("APNode",IWDNode.LEAD_SELECTION).createElement();
	dynEle.setAttributeValue("invoice", "1234545");
    }

But the invoice number isnt shown in my invoiceInputField. There is an inputfield with and id "invoiceInputField" btw.

Can anyone tell me what im doing wrong?

much thanks,

Hugo

Hi,

1)Create the node and attribute in the initmethod

IWDNodeInfo n= wdContext.getNodeInfo().addChild("APNode",null,true,true,true,false,true,true,null,null,null);

n.addAttribute("invoice","ddic:com.sap.String");

//getting child node

IWDNode n1= wdContext.getChildNode("APNode",0);

IWDNodeElement nel=n1.createElement();

String s1=new String("1234545");

nel.setAttributeValue("invoice",s1);

n1.addElement(nel);

2) Create inputField and bind the att.in the modify

//Get the root Container

IWDTransparentContainer trans=(IWDTransparentContainer)view.getElement("RootUIElementContainer");

//create the inputField

IWDInputField ip=(IWDInputField)view.createElement(IWDInputField.class,"input1");

ip.bindValue("APNode.invoice");

trans.addChild(ip);

Hope this helps,

Hi Vijayakhanna,

it works now. Much thx.

Hi,

Your addchild method adds a child with mandatoryselection = false. Later you retrieve the nodeInfo using lead_selection.

Try setting the mandatoryselection to true or try getChildNode("APNode",0).

Good luck,
