Saving Survey Error #41

Open rodavelino opened 12 years ago

rodavelino commented 12 years ago

When I edit a survey and try to save it, it says:

Problem with saving survey. Original error: error

The log shows the following:

@6b03ga1pn Internal Server Error (500) for request POST /surveyManager/saveSurvey

I get different error messages but the one that comes up the most is:

Internal Server Error (500) for request POST /surveyManager/saveSurvey

Execution exception (In /app/controllers/deserializer/QuestionObjectFactory.java around line 62) LazyInitializationException occured : failed to lazily initialize a collection of role: models.Category.questionCollection, no session or session was closed

Hope this helps.
