i am getting the following error any idea how to solve this
download the file in a table with binary attachment
context
+EmailOutDetails (parent)
.............--attachment (child)
.............--attachmentid (child)
.............--attachmentName(child)
.............--emailId (child)
.............--fileSize (child)
+attachment
+fileSize
if from the sample tutorial it is in the first level of the Context,
but if i have multiple attachment
i need to put it in EmailsOutDetail Node
it works in this way
IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IContextElement.ATTACHMENT);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
binaryType.setFileName(outMailDet.getAttachmentName());
binaryType.setMimeType(WDWebResourceType.UNKNOWN);
try{
wdContext.currentContextElement().setAttachment(attachment);
wdContext.currentContextElement().setFileSize(getFileSize(attachment));
}catch(Exception e){
System.err.println("Attachment file download exception:" +e.getMessage());
throw new WDRuntimeException(e);
}

If my question is not clear, i will elaborate more...
from the tutorial for file download, it is only single file,
if i have multiple file, i will put it in tables,
how do i change the code accordingly for the tables ,
i have to create a new node for tables for eg: EmailsOutDetail (Node) with the following attribute : attachment(binary), attachmentId, attachmentName, emailId, fileSize
the example is with attribute : attachment(binary), fileSize under the Context
the code below work
ArrayList detCol=new ArrayList();
byte[] attachment=outMailDet.getAttachment();
IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IContextElement.ATTACHMENT);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
binaryType.setFileName(outMailDet.getAttachmentName());
binaryType.setMimeType(WDWebResourceType.UNKNOWN);
try{
wdContext.currentContextElement().setAttachment(attachment);
wdContext.currentContextElement().setFileSize(getFileSize(attachment));
}catch(Exception e){
System.err.println(e.getMessage());
}
after that i change to :
for(Iterator it=col.iterator();it.hasNext();){
OutMailDetailsBean outMailDet=(OutMailDetailsBean)it.next();
elem=wdContext.createEmailOutDetailsElement();
elem.setAttachmentId(outMailDet.getAttachmentId());
elem.setAttachmentName(outMailDet.getAttachmentName());
elem.setEmailId(outMailDet.getEmailId());
byte[] attachment=outMailDet.getAttachment();
IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IEmailOutDetailsElement.ATTACHMENT);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
binaryType.setFileName(outMailDet.getAttachmentName());
binaryType.setMimeType(WDWebResourceType.UNKNOWN);
try{
elem.setAttachment(attachment);
elem.setFileSize(getFileSize(attachment));
}catch(Exception e){
System.err.println(e.getMessage());
}
detCol.add(elem);
}
wdContext.nodeEmailOutDetails().bind(detCol);
when i change my code for the emailsOutDetail (node) i hit the error? any idea ?

Hi ,
I got your requirement.
In your code..
for(Iterator it=col.iterator();it.hasNext();){
OutMailDetailsBean outMailDet=(OutMailDetailsBean)it.next();
elem=wdContext.createEmailOutDetailsElement();
elem.setAttachmentId(outMailDet.getAttachmentId());
elem.setAttachmentName(outMailDet.getAttachmentName());
elem.setEmailId(outMailDet.getEmailId());
byte[] attachment=outMailDet.getAttachment();
//change this line to
IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IEmailOutDetailsElement.ATTACHMENT);
//this..
IWDAttributeInfo attInfo=wdContext.nodeEmailsOutDetail ().getNodeInfo().getAttribute(IPrivateMailOutboundView.IEmailOutDetailsElement.ATTACHMENT);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
binaryType.setFileName(outMailDet.getAttachmentName());
binaryType.setMimeType(WDWebResourceType.UNKNOWN);- Mark as New

Hi ,
If you want to use the node EmailOutDetails for storing filedownload data..
Make sure that value attribute "attachment " under EmailOutDetails node.. is of type binary.
Second..
To set MIME information etc, you have to make the "attachement" value attribute inside the node as modifiablesimple type..
IWDAttributeInfo attInfo=wdContext.<b>nodeEmailOutDetails()</b>.getNodeInfo().getAttribute(IPrivateMailOutboundView.IEmailOutDetailsElement.ATTACHMENT);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();You have to say .. wdContext.node<nodename>().getNodeInfo()... and get that attribute.. u are getting node info of the context again..
