I'm trying to create a new attachment using the following code and I keep
getting a null pointer exception. My guess is that I'm not allowed to have
a null project area when creating a new attachment but I'm not able to find
any documentation or javadoc that mentions that. Also, when I look up
existing attachments and invoke the getProjectArea() method, all of them
return null so that makes me think that by not providing a project area, the
attachment is simply not associated with a specific project and can be
linked to by any workitem.

Can someone shed some light on this? Thanks!


Here is the code:
===============================================================
I first would iterate through existing work items finding the ones that had
references to attachments. I would then get that attachment handle:

IAuditableHandle handle = (IAuditableHandle) ((IItemReference)
ref).getReferencedItem();

if (handle instanceof IAttachmentHandle) {

// IAttachment attachment = auditableClient.fetchCurrentAuditable(handle,
IAttachment.FULL_PROFILE, monitor);

IAttachment attachment = auditableClient.resolveAuditable(handle,
IAttachment.FULL_PROFILE, monitor);

-------------------------------------------------------------------------------------------------
The "attachment" variable above is the "a" variable below. So I have a
fully resolved Attachment object and then I'm just trying to create an exact
copy of the existing attachment using the code below:
NOTE: pa = IProjectArea of the existing attachment and it is always null.


// Get the contents of the original attachment
ByteArrayOutputStream bos = new ByteArrayOutputStream();

serviceContent.retrieveContent(a.getContent(), bos, null);

byte[] content = bos.toByteArray();


// Create the new attachment in the repository

IAttachment attachmentNew = serviceNewWI.createAttachment(pa, a.getName(),
a.getDescription(), a.getContent().getContentType(),
a.getContent().getCharacterEncoding(), new ByteArrayInputStream(content),
monitor);

--------------------------------------------
The result is the following stacktrace:
