Every time I deploy my application to google app engine, the datastore for the app is cleared. Can this be turned off so that any data that is persisted to the datastore is not deleted between app re-deployments?
To deploy I right click on the project within Eclipse, select ‘google’ then select ‘Deploy to App Engine’
It might be the case that the datastore is not actually empty, and that something in your code is causing the data to not be displayed.
