update category value when two categories applied on a document.

Hi Expert,

need your help on below scenario.

Scenario: A document with two categories (Cat A and Cat are already applied.

we need to update a field value of category A only untouching Category B.

Below code snipet works fine to update the category A value, but some how its removing/deleting other category B entirely from document.. At the end of the script the document remains with Category A with updated value and all data with along with category get removed.

Pls suggest how to handle this situation. I tried using both method docManClient.updateNode(docNode) and docManClient.setNodeMetadata(320044, metadata1);,but the result is the same.

---------------------------------------------------------------------------------------------------------------------------

Node docNode = docManClient.getNode(320044);

StringValue fnametest = (StringValue) categoryTemplate1.getValues().get(0);

fnametest.getValues().clear();

fnametest.getValues().add("samtesting");

Metadata metadata1 = new Metadata();

metadata1.getAttributeGroups().add(categoryTemplate1);

try

{

docNode.setMetadata(metadata1);

docManClient.updateNode(docNode);// (nodeID, metadata);//.setNodeMetadata(320044, metadata1);

}

catch (SOAPFaultException e)

Thanks

Not sure where you are going wrong with code but I will try to walk you thru the loops correetly implement it correctly for your situation

Nomenclature-Node any Object that can be found in livelink whether folder,category,document,wfmap etc etc.Simply put you will see that in DTree.

Category-A Node of Object SubType 131

Metadata thru Categories-Category or Categories they themselves are valid Nodes applied to a Object so people can search on them later.

Now the AttributeGroups concept-A node can be put with a Category in which the Attributegroups will contain 1,when it is more than one it will contain more and think of it as an array of Categories.Now usually when you update an attribute in a category you may want to make sure that you dont touch what you dont want although many times the LLserver code is forgiving.

So here's how I would do it

GetNode(12345)

GetNodeMetadata() -if the node had metadata from 2 Categories its length would be 2 if nothing was there it would be empty.Use the Debugger on a NodeObject that has more than one category applied.

Now Loop through this array and look for the 'Description' that matches your category Name.If you don't find what you are looking for make sure you add a valid attributeGroup like

your way of reading it from a template.

Now this array will contain the individual Attributes that can be one of StringValue,IntegerValue,DateValue like that.Now if you were encountering a Set it will have a different class object.

Now again you want to match it on the attribute 'Description' of Interest and its values is a list of values as LL is designed so that it can hold

the values more than once.

Once you set it,you basically hit the upadate or setnodemetadata.

If you send a valid metadata structure OT will think you mean business,in all likelihood your code may only be sending one.I have no idea as I cannot read the code very clearly.

A week back I did a sample snippet Look at the one that says "How do you manipulate Multi Valued Attributes( MVA) Java Snippet" At your own peril you might try this .

You may want to try using the webgui because that is the bext debugger also try simple scenarios like a user adding more than one category to an object,that will be good.

Hi Sambit,

You're starting with a new Metadata object and then setting that onto the node. As you've discovered that will replace whatever the node has to the values you've set.

Instead, to update the existing metadata you'll want to get the metadata that is already assigned to the node, change the values, and then set it back.

So in your code, use:

Metadata metadata1 = docNode.getMetadata();

Hope this helps,

-chris
