The below works to effectively "hide" (i.e. so long as condition is true, editor presentation remains hidden) a String custom attribute but not so with an enumeration custom attribute.  Does the js need to change or is this behavior not supported for enumerations?  Js as follows:

dojo.provide("net.jazz.readonly.MaximoAppReadOnlyCondition.Condition");

dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");
dojo.require("dojo.string");
   
(function() {   
    /*
    * Answer true (read-only condition is met) if "Application" != "Maximo"
    */
    dojo.declare("net.jazz.readonly.MaximoAppReadOnlyCondition.Condition", null, {
   
    matches: function(workItem, configuration) {
        var conditionValueTrigger_maximo= "Maximo";
        var applicationValue= workItem.getLabel("application_enumeration");       
        var result = (applicationValue != conditionValueTrigger_maximo);
        console.log("Application Name=" + applicationValue + " result=" + result);
        return result;
    }
});
})();


NOTE: When condition trigger is reached, target custom enumeration is able to have contents modified and persisted (not possible when condition not satisfied) but I want the behavior to emulate the custom String attribute presentation and not show Enumeration at all if condition not satisfied--this is a convenient way to hide the drop-down list unless a trigger condition value is met on a dependent enumeration.

I know I can populate the target's value list to "somewhat" achieve this behavior but I do not want the enum to appear unless dependent condition is satisfied to avoid confusion.
