How put the creator of a workitem in a custom attribute

To make this actually match the question, see the script below.

This is a minimal calculated value that

1. Reads the work item state
2. Reads the work item creator name
3. Reads the work item creator UUID (needed for attributes of type contributor/user)
4. Logs some data
   
5. Returns the work item state value and the creator information as string

Configure it for the Description attribute and make it dependent on the state attribute to see what is happening.

In other contexts, you can return the creatorName to display the name or return the  creatorUUID, if this is an attribute of type contributor/user

            var creatorUUID = workItem.getValue(WorkItemAttributes.CREATOR);
            var creatorName = workItem.getLabel(WorkItemAttributes.CREATOR);
            var creatorInfo = "Creator is: " + "'" + creatorName + "'" + " UUID " + "'" + creatorUUID + "'";
            console.log(creatorInfo);
            var state = workItem.getValue(WorkItemAttributes.STATE);
            var stateInfo = "Value of state is: " + "'" + state + "'";
            console.log(stateInfo);
            return stateInfo + " " + creatorInfo;
        }
    });
})();

You might want to start understanding what types of scripts are available, which one to use and what the limitations of the current JavaScript API are. Read this section really carefully: https://jazz.net/wiki/bin/view/Main/AttributeCustomization#API_for_Javascript also consider to look at lab 5. It also talks about the limitations.

In addition, please carefully read How should I ask a question in the Forum if I want to receive useful answers? and consider to provide more information what you want to achieve with this.

The script above is a value set and not a calculated value as the classname suggests. It would return a pick list with one user, if configured correctly. Also if configured correctly you would see some odd string (the UUID) - which is what the contributor object returns. With getLabel(), you would get the user name - as string. Dependent of what the type of the attribute is, this might or might not be working as expected, because of said limitations of the API.

Because it is incorrect as you would have seen if you had looked into the log files.
This script works

dojo.provide("org.example.workitems.providers.AssignCalcValue");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

(function() {
     var WorkItemAttributes=com.ibm.team.workitem.api.common.WorkItemAttributes;
    dojo.declare("org.example.workitems.providers.AssignCalcValue", null, {


        getValueSet: function(attributeId, workItem, configuration) {
               
        console.log("1");
        var creat= workItem.getValue(WorkItemAttributes.OWNER);
        console.log("owner :" + creat);
        console.log("2");
        var result= [];
result.push(creat);
        return result;
}
});
})();

and returns the owner after the owner has been set and if dependencies are set.
Note, it picks the Owner not the creator, the creator is in

• WorkItemAttributes.CREATOR

From https://jazz.net/wiki/bin/view/Main/AttributeCustomization#API_for_Javascript again see:

Only values of the following attribute types can be safely read by and returned from scripts:

• Short String
• Medium String
• Large String
• Integer
• Long
• Decimal
• Boolean
• Timestamp
• Limited support for Enumeration.
• Limited support for Items

Owner is an item. You can return the UUID (not the ID) as a value if you have one, you can not search for them, the Label returns the user name.

With a calculated value and getLabel of Creator I get the name of the Creator but I can't put it in my customize attribute.

dojo.provide("org.example.workitems.providers.AssignCalc");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

(function() {
var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;

dojo.declare("org.example.workitems.providers.AssignCalc", null, {

getValue: function(attribute, workItem, configuration) {
        console.log("1");
        var creat = workItem.getLabel(WorkItemAttributes.CREATOR);
        console.log("createur :" + creat);
return creat;
}
});
})();

I tried with your script with getValueSet and getValue of owner

the script doesn't do the trip the custom attribute is list of contributor type

Sorry but I tried with the script down and Etat is null :

dojo.provide("org.example.workitems.providers.Validator");
 dojo.require("com.ibm.team.workitem.api.common.Severity");
 dojo.require("com.ibm.team.workitem.api.common.Status");

 (function() {

 var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;

     dojo.declare("org.example.workitems.providers.Validator", null, {

         validate: function(attribute, workItem, configuration) {
    var Category= workItem.getValue(WorkItemAttributes.FILED_AGAINST);
    var Status= com.ibm.team.workitem.api.common.Status;
    var Etat= workItem.getValue(WorkItemAttributes.state);
    console.log("HERE IS Etat VALUE" + " " + Etat);
             console.log("HERE IS catégorie VALUE" + " " + Category);

This is a minimal calculated value that

1. Reads the work item state
2. Returns the work item state value

Configure it for the Description attribute and make it dependent on the state attribute to see what is happening.

I have now seen the same incomplete code in many similar questions and I can not see any systematic approach of reading documentation, starting with minimal scripts and incorporating suggestions in the discussion on this and other related questions. This does not make me very optimistic that this is going anywhere.

Thank you this is ok with the sript down :

dojo.provide("org.example.workitems.providers.Validator");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

dojo.require("com.ibm.team.workitem.api.common.Status");

    var Severity= com.ibm.team.workitem.api.common.Severity;

    dojo.declare("org.example.workitems.providers.Validator", null, {

    validate: function(attributeId, workItem, configuration) {
    var Category= workItem.getValue(WorkItemAttributes.FILED_AGAINST); 
var Etat= workItem.getValue(WorkItemAttributes.STATE);
console.log("HERE IS Etat VALUE" + " " + Etat);
console.log("HERE IS catégorie VALUE" + " " + Category);
if (Etat === "Enchainement_activites_anomalie.state.s1" && Category !== '_Ii-KkMjyEeWM1dgCThyTQQ'){
        return new Status(Severity["ERROR"], "Echec Validation. Merci de renseigner Classé dans");

else

});
