copy model node to value node

[Former Member]

i have a table ....which i populate my table with the model node....

when i put this code i get an incompatible node exception

wdContext.currentContextElement().getTableFilter().filter(wdEvent,wdContext.nodeProductCommandBean wdContext.nodeProduct(),wdContext.nodeVnFilters());

copy model node to value node will result in incompatible node...

wat is the solution for this....

for instance when using table filter

wdContext.currentContextElement().getTableFilter().filter(wdEvent,wdContext.nodeProductCommandBean wdContext.nodeProduct(),wdContext.nodeVnFilters());

Hi,

I Have faced the similar situation before, where i have to copy some of the model node values to value node structure. And since both structures are different you cannot use the copy service.

What you can code is loop over the model node , fetch the values ...then create the value node elements and keep addign them to a java.util.List. And at last bind that list to your value node.

Code Should Look Like this

java.util.List lst = wdContext.current<ModelNode>Element().modelObject().get<Model>Response_Sync().get<ListOfElements>(); 
	  java.util.List newList =  new java.util.ArrayList();   
  
	  IPublic<Component>.I<ValueNode>Element sData = null; 	  
  
	  for (int i =0; i < lst.size(); i++){
		sData = wdContext.create<ValueNode>Element(); 
  	
		com.sap.model.so007qr.<ModelNode> so = (com.sap.model.so007qr.<ModelNode>)lst.get(i);
		
			sData.setAttributeOne(so.getAttributeOne());
			sData.setAttributeTwo(so.getAttributeTwo());
			sData.setAttributeThree(so.getAttributeThree());

		newList.add(sData);
	  }
  	    
	  wdContext.nodeSalesData().bind(newList);

Hi,

I'm doing that with:

//IT WORKS
WDCopyService.copySubtree((IWDNode)ModelNode,(IWDNode)ValueNode);

It works fine but it doesn't work in the reverse manner:

//IT DOESN'T WORK
WDCopyService.copySubtree((IWDNode)ValueNode,(IWDNode)ModelNode);

actually i am iterating the node

int size = wdContext.node<modelnodename>.size();

IPrivate<viewname>.I<Valuenodename>Element ele;

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

{

ele = wdContext.create<valuenodename>element();

ele.setname(wdContext.node<modelnodename>.get<modelnodename>elementat(i).getname();

ele.setPrive(wdContext.node<modelnodename>.get<modelnodename>elementat(i).getprice();

wdContext.node<valuenodename>.addelement(ele);

}

though copysubtree is a good idea..i will try...

Can u explain what is the exact error you are getting ?

Copying data from model node to value node will not cause any error if they share same structure.

It is sample structure...

modelnode

- name

-price

valuenode

-name

-price

Exception : Incompatible Node

hi,

try out this.

int size = wdContext.node<modelnodename>.size();

IPrivate<viewname>.I<Valuenodename>Element ele;

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

{

ele = wdContext.create<valuenodename>element();

ele.setname(wdContext.node<modelnodename>.get<modelnodename>elementat(i).getname();

ele.setPrive(wdContext.node<modelnodename>.get<modelnodename>elementat(i).getprice();

wdContext.node<valuenodename>.addelement(ele);

}

Try out this code.

Hi,

If both the model and value node are of the same structure. Then you can use

WDCopyService.copy........();

function to transfer the data in one shot.

please, describe in more details: what do you mean "copy model node to value node", and "incompatible node".

clear question is half of an answer
