1) We have two different output panel in existing component it is rendering the based on dataModel.isAttachment true or flase

Bobcat Category Hierarchy is a custom objecct

if(CmsBusinessProduct.isClassificationHierarchy){
dataModel.isAttachment = true;
}else{
dataModel.isAttachment = false;
} 

<apex:outputPanel rendered="{!dataModel.isAttachment}">
<div ng-if="!params.specPack" class="widget-contents" ng-include="tplPrefix+'/productDetails.html'">Loading...</div>
<div ng-if="params.specPack || printPreparation.enabled" ng-style="(!params.specPack ? {'display':'none'}: {})" ng-include="tplPrefix+'/specPack.html'"></div>   
</apex:outputPanel>                        
<apex:outputPanel rendered="{!!dataModel.isAttachment}">
<gpim-isolated-scope gpim-products="{!dataModel.productCode}" gpim-context-category="{!dataModel.productCategory}">
<div ng-if="!params.specPack" class="widget-contents" ng-include="tplPrefix+'/productDetails.html'">Loading...</div>
<div ng-if="params.specPack || printPreparation.enabled" ng-style="(!params.specPack ? {'display':'none'}: {})" ng-include="tplPrefix+'/specPack.html'"></div>   
</gpim-isolated-scope>  
</apex:outputPanel> 
 
Do we need to keep both panels 
2) Currently I am using the new apex class.Do we need to use GUID?  








I have gone through the existing logic for attachments specs. it is rendering based on the Bobcat Category Hierarchy is a custom object.
List<Bobcat_Category_Hierarchy__c> categories =  [select Id, Name, Label__c, Lifecycle_Status__c
                from Bobcat_Category_Hierarchy__c
                where Name = :categoryName
                and Bobcat_CategoryHierarchyId__r.Name = 'Bobcat Offerings'
                and AncestorId__r.Name = 'Attachments'
                and (Visibility__c = 'Dealers' or Visibility__c = 'Public')
                and (Lifecycle_Status__c = 'Active' or Lifecycle_Status__c = 'Discontinued')]; 
				
				
========================================================================================================		
if(CmsBusinessProduct.isClassificationHierarchy) {
				hw.isAttachment = true;
				//Bobcat_Category_Hierarchy__c.Name ===> 'compactNAAugerAttachment'
				hw.attachmentCategory = CmsBusinessProduct.getUniqueCode();
				hw.productCode = '';
				hw.productCategory = '';
			} else {
				hw.isAttachment = false;
				hw.attachmentCategory = '';
	
				if (currentModel != null) {
					 hw.productCode = currentModel.ProductCode + ':CompactNA';
					 hw.productCategory = currentModel.Contract_Code__r.GPIMContextCategory__c;
				}
			}	
========================================================================================================
public static String getUniqueCode() {

		return null;

currentClassificationHierarchy = CmsDal.getAttachmentCategoryByName(CmsBusiness.routeParam);

            if (!categories.isEmpty()) {
