How Do I Access The DocumentStore From Within A Class?

[flynn]

Good Afternoon, All:

How do I access the DocumentStore from within a class?

What notations and imports need to be made?

What code should I use to do this?

Please be as specific and detailed as you can. I hate to ask, but the answer is not as intuitive as I'd hoped, and the only examples of code that I've found haven't worked. I'm hoping that a direct appeal will help me move forward past this roadblock.

With Regards,

Try DocumentStore.instance(), what are you trying to do?

Man, that was easy. I'm trying to get the contents of the DocumentStore after it generates a PDF, so that I can write it out to a file instead of to the browser.

I was trying to use Ben Catherall's approach as described in this thread:
http://www.seamframework.org/Community/PDFdocumentStore

However, conversation doesn't work like he has in his code (there is no get(String) method for Conversation), so I'm now trying to access the DocumentStore directly.

Now I have to figure out how to get the document's id String so that I can get the DocumentData, since the DocumentStore's getDocumentData method requires an id String.

Any clues or suggestions?

I'm just brainstorming here but looking at the source code in the UIDocument encodeEnd I see something like

        if (sendRedirect) {
           // The stuff that puts data in DocumentStore and redirects
        } else {
            UIComponent parent = getParent();

            if (parent instanceof ValueHolder) {
                ValueHolder holder = (ValueHolder) parent;
                holder.setValue(documentData);
            }

which could indicate that if you set sendRedirect=false in the UIDocument, the data should end up in the parent, as long as it is a ValueHolder.

I've never used it so just guessing: If you set sendRedirect to false and nest the UIDocument in something with a value-binding, the byte[] data ends up there?

My bad in the code before its a Context object, not Conversation object

conversation = Contexts.getConversationContext()
