Please share with me if have any idea

Hi

Code in following manner

IPublic<your view>.I<node element> elementObject = wdContext.node<node name>().create<node element name>();

elementObject .set<feild>(.......value......);

.

.

. //set all feilds.

.

wdContext.node<node name>().addElement(elementObject );

Hi,

Am using CE7.2 SP3 here am posting the some peace of code where am creating the element for the Node and adding

for(int i=0;i<lstInteractionEmployeeDTO.size();i++)

{

if(!arrInbox.contains( lstInteractionEmployeeDTO.get(i).getFkIdInteraction() ))

{

IPublicEwd_inboxmgtComp.IDisplayElement ele = wdContext.nodeDisplay().createAndAddDisplayElement();

arrInbox.add( lstInteractionEmployeeDTO.get(i).getFkIdInteraction());

ele.setInteractionShortDesc(lstInteractionEmployeeDTO.get(i).getSubject());

if(lstInteractionEmployeeDTO.get(i).getReceivedDate()!=null){

ele.setInteractionDate(new java.util.Date(lstInteractionEmployeeDTO.get(i).getReceivedDate().getTime()));

}

}

*Note : error is not throwing always randomly its hitting in pre production the same code is working very fine with all other boxes.

Hi,

You should add element created into the node. Here in your code you have not added it. Adding element might resolve your problem.

for(int i=0;i<lstInteractionEmployeeDTO.size();i++)

{

if(!arrInbox.contains( lstInteractionEmployeeDTO.get(i).getFkIdInteraction() ))

{

IPublicEwd_inboxmgtComp.IDisplayElement ele = wdContext.nodeDisplay().createAndAddDisplayElement();

arrInbox.add( lstInteractionEmployeeDTO.get(i).getFkIdInteraction());

ele.setInteractionShortDesc(lstInteractionEmployeeDTO.get(i).getSubject());

if(lstInteractionEmployeeDTO.get(i).getReceivedDate()!=null){

ele.setInteractionDate(new java.util.Date(lstInteractionEmployeeDTO.get(i).getReceivedDate().getTime()));

}

wdContext.nodeDisplay().addElement(ele); // This line was missing.

}

Try this hope you get resolved with the problem.

Hi Deepak,

IPublicEwd_inboxmgtComp.IDisplayElement ele = wdContext.nodeDisplay().createAndAddDisplayElement();

createAndAddDisplayElement() will creates ele and adds to that doesn't need add explicitly.

Hi,

Create an element of that context node in the wdInit of the view.

Thanks & Regards

Hi Rajesh,

This error often occurs when you try to set value for any element in a node whose cardinality is 0....n . To overcome this problem you should first create the element then add it the node.
