Answer: B,D

Explanation:

B: formContext.ui.refreshRibbon(refreshAll);

Causes the ribbon to re-evaluate data that controls what is displayed in it.

Indicates whether all the ribbon command bars on the current page are refreshed. If you specify false, only the page-level ribbon command bar is refreshed. If you do not specify this parameter, by default false is passed.

Remarks: This function is typicaly used when a ribbon (RibbonDiffXml) depends on a value in the form. After your code changes a value that is used by a rule, use this method to force the ribbon to re-evaluate the data in the form so that the rule can be applied.

D: If role is there – just refresh the ribbon to see the button if (isButtonEnabled) { formContext.ui.refreshRibbon();

}

},
