Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

2. Follow the instructions here
http://code.google.com/p/google-feedserver/wiki/SettingUpADevelopmentEnvironment
3. run the server with derby and hit http://localhost:8080/example.com/.contact

http://code.google.com/p/google-feedserver/wiki/SettingUpADevelopmentEnvironment

What is the expected output? What do you see instead?
Feed with contacts

Exception
http://code.google.com/p/google-feedserver/wiki/SettingUpADevelopmentEnvironment

What version of the product are you using? On what operating system?
Ubuntu, r354

Please provide any additional information below.

File:com.google.feedserver.samples.adapters.IBatisCollectionAdapter
Method: getRequestParams(context)

This happens because the userInfo param in request context is null and
there is an access on UserInfo without null check.

UserInfo userInfo = getUserInfoForRequest(request);
params.put("opensocial_viewer_email", userInfo.getEmail()):

A simple null check resolves the issue and i can the see the feeds.
params.put("opensocial_viewer_email", 
        (userInfo != null ) ? userInfo.getEmail() : "user@example.com");

I am not completely aware of the use-case and if defaulting the email is
OK? Submitting a patch anyway (Attached)
