Upload document - "Document Type is required field" error

Hi,

Following the code samples for uploading documents to LL server (https://knowledge.opentext.com/knowledge/cs.dll/fetch/2001/15080935/-15106263/15106294/15106295/16376487/17990637/45500683/upload_C#.html) I'm getting the error "Dispatched service DocumentManagement threw exception DocMan.NodeCreationError : Document Type is a required field" in this line:

string objectID = contentServiceClient.UploadContent(ref otAuth, contextID, fileAtts, fileStream);

Could you please advice how Document Type should be defined?

Thanks,

Alex

The easiest avenue for you is to get the link of the webui a URL to the livelink you are working and do 'Add Document' .If a category screen pops up and you see a yellow icon that says "Document Type" that means the document controllers on that folder needs you to supply metadata.Your CWS code cannot work around livelink business rules.

I wonder how one could debug livelink if Fiddler, Wireshark and Softerra LDAP browser was not invented and not free

Hi Appu,

Yes, web UI asked me to provide Document Type for adding new document. Where should I do it in the code?

Thanks,

The term for a data structure for category/attribute is metadata.Truthfully it stands for any type.So the pseudo code for doing this is

Get from livelink the category object with default values or from the folder if it is applied
Parse the object using the different classes OT has given in all possibilty it has to belong to one of these StringAttribute,IntegerAttribute & DateAttribute
Create a constructor for each leaf and decide how many values you are going to give it.In livelink each attribute can hold more than one
Now create your node using that passing metadata in the call.

Here's a sample that used to work in my blog https://appukili.wordpress.com/2013/03/22/how-to-parse-a-nodes-categories-in-c-wcf-code/ this shows you if you have a node with metadata how would you take it and print what you see in the GUI.

Extended that same code to change things in a category

https://appukili.wordpress.com/2014/04/16/so-you-want-to-change-categoriesattributes-of-a-object-in-livelink-via-cws/

Here's a completely hard coded approach to how you can attach a piece of metadata,it is a zip file containing a C# sln file and a read me.Do not try the end points I have in the document because I have the server down.

All the code that I produce is made by looking at OT produced code and using my imagination on how it could be so if you want to stick to OT code see the sample that creates a a category and adds a document.@Conocophillips I doubt if you will get category creation privileges in a system.

Thanks Appu! I'll follow these links.

While you create theContextID for your new document upload, you would essentially call the DocMan.createDocumentContext() first.

There is a parameter of return typeMetadata in this call.

This is where you would be adding the metadata information (category) together with the values (Documents Type) for this particualr document.

The next time you use this contextID with UploadContent, you shouldn’t have an issue.

Hi guys,

Thank you for info and links, I got it working.

By any chance, can I get some code samples for creating folders and deleting files using CWS?

Thanks,

Alex
