Leaving Sugarizer app without leaving current activity cause some activities to become empty

[llaske]

It's possible to leave Sugarizer when an activity is still running: by closing the browser or by quitting the app.
In that case when the activity is relaunch, the content of the activity is empty.
Of course it's not a good idea for the user to leave activity on this way because it could lost its current work but having an empty context is not a good experience.

It happens (at least) in Vote, Curriculum, Ebook Reader, Exerciser activities.

@dhruvmisra, could you have a look on it? I guess it could be solve by saving the Journal instance when the context is load.

Hmmm, is the journal entry modified right after accessing it from the datastore? I'm not sure why that would happen.

[llaske]

I guess it's because the Journal entry is empty.
The Journal entry is created automatically by Sugar-web when a new instance is launched. So if the instance has no opportunity to save it - usually done on Stop event - the entry content is still empty.

[dhruvmisra]

Oh right, it's a new instance. Okay I'll save the context right when the activity (new instance) is loaded.
