How to use Lightning Component to update records on server
How can I get values selected on a drop down by a user to save to the records? I believe my issue is in my JS controller "changeDcn"..
Component:
<!--massUpdateItemDecision--> <aura:component access="global" controller="MassUpdateController" implements="flexipage:availableForAllPageTypes,force:lightningQuickActionWithoutHeader,force:hasRecordId,force:hasSObjectName"> <aura:handler name="init" value="{!this}" action="{!c.doInit}"/> <aura:attribute name="recordId" type="Id"/> <aura:attribute name="relatedItems" type="MassUpdateController.wrapItemRecord[]"/> <aura:attribute name="selectedItems" type="MassUpdateController.wrapItemRecord[]"/> <aura:attribute name="itemDecisionList" type="String[]"/> <aura:attribute name="selectAll" type="boolean" default="false"/> <aura:attribute name="selectedDecision" type="String"/> <aura:attribute name="RIM__c" type="Object"/> <aura:attribute name="RIM_Item__c" type="Object"/> <force:recordData aura:id="rRecord" recordId="{!v.recordId}" targetFields="{!v.RIM__c}" layoutType="FULL" mode="EDIT"/> <lightning:card iconName="custom:custom41" title="{!
