How to add custom attributes to work items programmatically

0
Lin Ye (306●3●26●11) | asked Mar 22 '10, 11:00 a.m.
Hi,

Can I ask how to add a custom attribute to a work item programmatically? Suppose the custom attribute is:

Name: JiraKey
ID: jiraKey
Type: Small String

We cannot add this attribute through Project Configuration > Configuration Data > Work Items > Types and Attributes in advance because we don't know what are the specific custom attributes we are going to add at compile time. Let me use the above attribute as an example, how can I add it to a work item directly? Any documentation or tutorial about this? thank you very much

Lin

here is the code I tried

IAttribute attribute = workItemClient.createAttribute(projectArea, "testJiraKey2", "Small String", "Test Jira Key", null);
System.out.println("attribute id: " + attribute.getIdentifier());


workItem.addCustomAttribute(attribute);
workItem.setValue(attribute, "JRM-Test");



Then I got the exceptions:
attribute id: TestJiraKey2

I modified the code to get rid of the above the exception:

IAttribute attribute = workItemClient.createAttribute(projectArea, "testJiraKey5", "Small String", "TestJiraKey", null);


IWorkItem workItemFromCopy = workingCopy.getWorkItem();
workItemFromCopy.addCustomAttribute(attribute);
workItemFromCopy.setValue(attribute, "JRM-Test");

But then I got some new exceptions

java.lang.ClassCastException: java.lang.String incompatible with com.ibm.team.workitem.common.model.Identifier

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

Any idea?

"Small String" is not a valid attribute type and will be interpreted as
a custom enumeration. Setting enumeration values requires Identifiers
(that are read from the enumeration).

As you need a string attribute, change the attribute creation code to read:

IAttribute attribute = workItemClient.createAttribute(projectArea,
"testJiraKey5", AttributeTypes.SMALL_STRING,
"TestJiraKey", monitor);
