I am using ODK to collect info remotely from an Android phone. Everything
was working fine until a few days ago. The App Engine has been error out
and I have been unable to delete forms create for ODK Collect. Any help
would be great. See error below:
Uncaught exception from servlet
java.lang.ClassCastException: com.google.appengine.api.datastore.Key
