This is my first foray into Custom Enumerations with the SDK, and I hit a problem I'm not sure what is ...

After I login and get the workItemClient, I attempt to get the values of a custom enumeration where the attributeTypeId = "themeEnum" and the name = "themeEnum".

So I went to findAttribute of the "themeEnum" which is the ID in the process configuration source, and then
IAttribute attribute0= workItemClient.findAttribute(myProjectArea, "themeEnum", monitor);
IEnumeration<?> enumeration= workItemClient.resolveEnumeration(attribute0, monitor);

Eventually, I need to map a string value passed in through these enumerationLiterals to be able to set the enumeration programmatically.

However, I am getting a NullPointer:
Exception in thread "main" java.lang.NullPointerException
at com.ibm.team.workitem.client.internal.AuditableClient.resolveAuditable(AuditableClient.java:134)
at com.ibm.team.workitem.common.internal.EnumerationManager.resolve(EnumerationManager.java:168)
at com.ibm.team.workitem.common.internal.WorkItemCommon.resolveEnumeration(WorkItemCommon.java:453)
at com.ibm.ws.build.rtc.OpenFeature.main(OpenFeature.java:68)


I'm not sure what could be wrong since I have so very little code so far.

List<IAttribute> listAttributes = workItemClient.findAttributes(myProjectArea, monitor);

for (IAttribute attribute : listAttributes) {

	System.out.println(attribute.getIdentifier()); // or getDisplayName()

}

Yes .. I had already somewhat determined that it was because it didn't find a "themeEnum" attribute, but I have double-checked in my project project process config that the name and attributeTypeId both are "themeEnum".

IEnumeration<ILiteral> enumeration= (IEnumeration<ILiteral>)workItemClient.resolveEnumeration(attribute, monitor);

List<ILiteral> enumerationLiterals = enumeration.getEnumerationLiterals();

for (ILiteral literal : enumerationLiterals) {

	System.out.println(literal.getIdentifier2().getStringIdentifier() + ' ' + literal.getName());

}

	public Identifier getIdentifier(IAttribute attribute, String displayName) {

		IEnumeration<ILiteral> enumeration;

		try {

			enumeration = (IEnumeration<ILiteral>)workItemClient.resolveEnumeration(attribute, null);

			List<ILiteral> enumerationLiterals = enumeration.getEnumerationLiterals();

			for (ILiteral literal : enumerationLiterals) {

				if (literal.getName().equalsIgnoreCase(displayName)) {

					return literal.getIdentifier2();

				}

			}

			return null;

		} catch (TeamRepositoryException e) {

			return null;

		}		

	}

IAttribute attribute0= workItemClient.findAttribute(myProjectArea, "themeEnum", monitor); 

if ((attribute0!=null) && (workItem.hasAttribute(attribute0))) {										

	workItem.setValue(attribute0, getIdentifier(attribute0, "Capability"));

}

I am attempting to create a WorkItem programmatically, and I have almost all of it completed. My last item is to set the value into a field which is backed by an Enumeration. (forgive me if my terminology is off).

I am able to create my WorkItem via the Eclipse client and then "dump" the data out programmatically. My "dump" shows this:
Quality Attributes : qualityAttributes.literal.l6,qualityAttributes.literal.l12

my attribute display name is "Quality Attributes" and it is displayed as a multi-select list in the UI, and it has 2 items "selected", hence you see the literal.l6 and l12.

Programmatically, what I have is the display of those literals, basically "Capability" and "Documentation". I can easily go into my process config and hardcode into my java that "if display.equals("Capability") then use "qualityAttributes.literal.l6", but I was hoping to be able to get all of the Enumeration items, and compare the display name to what I need, and then use that literal value.

I've tried a couple things that I have found in the forums, but nothing quite works to get what I need, which is all available items defined in the Enumeration itself, not the values of a specific attribute. As well, I had a hard time finding a way to go from the displayName to the literal value, instead of the other way around (which seems rather easy).

....

Identifier<extends> literalID=getLiteralStartsWithString(points, workItemCommon, ia);

if(literalID!=null)	

  workItem.setValue(ia,literalID);				

....



	private static Identifier<extends> getLiteralStartsWithString(String name, IWorkItemCommon workItemCommon, IAttributeHandle ia) throws TeamRepositoryException{

		Identifier<extends> literalID=null;

		IEnumeration<extends> enumeration= workItemCommon.resolveEnumeration(ia, null);



		List<extends> literals = enumeration.getEnumerationLiterals();

		for (Iterator <extends> iterator = literals.iterator(); iterator

				.hasNext();) {

			ILiteral iLiteral = (ILiteral) iterator.next();

			System.out.println("Literal: " + iLiteral.getName() + " id: " +iLiteral.getIdentifier2());

			if(iLiteral.getName().startsWith(name)){

				System.out.println("Literal Found... " + iLiteral.getName() + " " + iLiteral.getIdentifier2());

				literalID = iLiteral.getIdentifier2();

				break;

			}

		}

		return literalID;

	}

I'm not sure if I did understand it right... I think that you need an ILiteral object. This piece of code might help you to figure out

I suppose you already have an IAttribute object, found with findAttribute() method.

IEnumeration<ILiteral> enumeration= (IEnumeration<ILiteral>)workItemClient.resolveEnumeration(attribute, monitor);

List<ILiteral> enumerationLiterals = enumeration.getEnumerationLiterals();

for (ILiteral literal : enumerationLiterals) {

	System.out.println(literal.getIdentifier2().getStringIdentifier() + ' ' + literal.getName());

}

The code above will list all literals and names for a given enumeration (resolved by an attribute).

So, I imagine that you want some function like this one:

	public Identifier getIdentifier(IAttribute attribute, String displayName) {

		IEnumeration<ILiteral> enumeration;

		try {

			enumeration = (IEnumeration<ILiteral>)workItemClient.resolveEnumeration(attribute, null);

			List<ILiteral> enumerationLiterals = enumeration.getEnumerationLiterals();

			for (ILiteral literal : enumerationLiterals) {

				if (literal.getName().equalsIgnoreCase(displayName)) {

					return literal.getIdentifier2();

				}

			}

			return null;

		} catch (TeamRepositoryException e) {

			return null;

		}		

	}

Then you use like this:

IAttribute attribute0= workItemClient.findAttribute(myProjectArea, "themeEnum", monitor); 

if ((attribute0!=null) && (workItem.hasAttribute(attribute0))) {										

	workItem.setValue(attribute0, getIdentifier(attribute0, "Capability"));

}
