Conference Management App - Create a Lightning Component with Server-Side Apex Controller:

Step 5: Add Component to the Speaker Record Page
Click App Default and then Assign as App Default.
Select the Conference app, then click Next and then Save.
Question: Does anyone know why Conference Management App is not listed for selection?


I am also getting this error when I verify the hands on challenge:Note all APEX codes saved without errors. and all other steps worked.
Step not yet complete... here's what's wrong:
There was an unexpected error in your org which is preventing this assessment check from completing: System.QueryException: List has no rows for assignment to SObject

Thanks in advance for your help.

Hi All,
If any one finds difficulties in passing this challenge plz make changes in the VF page:
<apex:outputText value="{!sampleMergeField1}"/> <apex:outputText value="{!HTMLENCODE(sampleMergeField2)}" escape="false"/> <apex:outputText > {!sampleMergeField3} </apex:outputText> <script> document.write('{!JSINHTMLENCODE(sampleMergeField4)}'); </script> {!sampleMergeField5} <script> var x = '{!JSENCODE(sampleMergeField6)}'; </script> <apex:outputLabel value="{!HTMLENCODE(sampleMergeField7)}" escape="false"/>

Thanks,
Ram
