AEM 6.2 SP1 communities QnA feature not working

Recently I tried QnA feature in Adobe Communities but the functionality is not working correctly. There is a js error which is blocking the functionality to work.

JS Error

 /etc/clientlibs/social/commons/scf/scf.js - line no 357

 getForm: function(form) {
            return this._forms[form];
}

In above code this._forms is coming as null and breaking the QnA functionality

Modified above code as below to fix js error 

getForm: function(form) {
            if (typeof this._forms === 'undefined') {
                return null;
            } else {
                return this._forms[form];
            }
        }

QnA is working fine after making above changes and seems the issue is present in AEM 6.2 SP1 CFP 18, CFP 19.

Updated adobe with above fix

AEM integration with Akamai Fast Purge API for Single/multiple urls

Image
In AEM we can clear dispatcher cache on page activation by adding dispatcher flush agent but if we have Akamai on top of dispatcher as CDN then we need to manually clear Akamai Cache by going to akamai console. Akamai provides fast purge API and using that we can clear page cache using single URL, CPCode, multiple urls etc We can integrate Akamai Fast Purge API with replication agent so that for every page activation akamai cache gets cleared. To integrate with Akamai Fast Purge we need below details (Contact Akamai for details related to your account) 1) Access Token 2) Client Secret 3) Client Token 4) Akamai Host API End Points ( https://developer.akamai.com/api/core_features/fast_purge/v3.html ) Once above details are gathered you can refer below code for multiple urls cache clear Create a map with array list of urls  Map<String, List<String>> akamaiRequestMap = Maps.newHashMap(); ArrayList<String> arrayList = new ArrayList<>(); arrayList.add("Ad

AEM - Rollout a page programmatically and update references

 Out of the box RolloutManager provides below 3 methods by using that we can rollout the page programmatically. 1) void rollout(RolloutParams params) throws WCMException; 2) void rollout(ResourceResolver resolver, LiveRelationship relation, boolean reset) throws WCMException; 3) void rollout(ResourceResolver resolver, LiveRelationship relation, boolean reset, boolean autoSave) throws WCMException; But when using 2nd and 3rd method we are able to rollout the page but the link references are not getting updated to the corresponding locale. This is because we are not providing the rollout trigger in 2nd and 3rd methods, so referenceUpdate is not getting triggered.  In order to update the link references in the rollout page we need to use 1st method and pass/set the required details in RolloutParams class. Below is example code for setting the RolloutParams                                              RolloutParams rolloutParams = new RolloutParams();
