How to change work item type programmatically when attribute value changes?

I'm trying to determine the best API or programmatic approach to change the work item type when a radio button value changes.

Can anybody give me any pointers on this?

Thanks in advance.

I tried it out and this script seems to do it (This is an example and not fully tested and I am not liable if the script causes issues etc.). There are various considerations e.g. for which types to work and what to return and why that I leave to the reader.

This script only looks at items with a type defect and task and based on the priority it sets a type or returns the current type. Priority is looked for using the display value and not the literal ID.

dojo.provide("com.example.ValueProvider");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");
(function() {

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

    dojo.declare("com.example.ValueProvider", null, {

        getValue: function(attribute, workItem, configuration) {
        	var enumerationDisplayValue = workItem.getLabel(WorkItemAttributes.PRIORITY);
       		// var enumerationLiteral = workItem.getValue(WorkItemAttributes.PRIORITY);
       		var currentType = workItem.getValue(attribute);
       		if(currentType=="defect" || currentType=="task"){
				if(enumerationDisplayValue=="High"){
					return "defect";
				} 
				if(enumerationDisplayValue=="Medium"){
					return "task";
				}
			}
			return currentType;
        }
    });
})();

In general you set the ID of the type in the attribute.

I can think of the following approaches you can try:
1. A JavaScript based attribute customization. See https://jazz.net/library/article/1093 Lab 5 and https://jazz.net/wiki/bin/view/Main/AttributeCustomization. You would return the type ID based on the enumeration literal each time. I would assume the user has to refresh the editor if that happens.
2. A follow up action coded in Java - this is a lot more complex and has to deployed on the server.  I would try the 1st approach on a test system

I would also - as always - ask myself the question, if this is a good approach. Why do we have this requirement? Is there a better way? Should a human do this change?

aren't there potential impacts to other attributes in the target workitem type if they are not 100% symmetrical.  

I haven't tried JavaScript, however, I used the API. I think it should work - as always test this on a test system, obviously.

If the other work item type has new attributes, they will be created. If the editor presentations are different, after reload attributes not in the presentations will not be shown, but they will still be there.
If there is validation or different required attributes then you would have to fix that in the UI.

As far as I am aware you can not change an attribute type at all. See https://jazz.net/library/article/1002 for best practices. As far as I know the only way to create a new attribute type properly requires modification of the process XML by the admin tools.

Not 'attribute', complete workitem type..

he wants to change from task to story, or to defect, or a custom workitem type

Stupid me....

I should have been more clear about what I meant. But, yes I'm changing from incident to an issue work item.
