Hi,
I am having a big problem with my GAE Project.
I want to store some Contact data and that worked perfectly.
Since i do not like the way GAE generates the keys, I am now using the
String ID to define my own key. Worked also.
To have running numbers, created a table that holds some counters and
added handling for those in the Contact storage. It fetches the
contact counter, adds 1, stores it back.
But now, my addcontact does not work anymore.
I even tried to roll back to the last working state but it keeps
throwing null pointer errors.
