Hi All,

When I have tried to execute the query as 
        "Select Id, Subject from ActivityHistory"

in 'Query Editor' from the developer console in the context of 'System Administrator'.

After executing the query, I got the error as  "entity type ActivityHistory does not support query"

Can anybody will help me how to solve this error?

Thanks 

Hi,

I'm having this issue when I click on "New Note" Button: The button is not working.


<apex:relatedList list="AttachedContentNotes"/>

Any clue? 

I can add notes without using my visualforce page, using the defalut layout.

Thanks,

Pablo G.
