Re: Null pointer in Cayenne 2.0.3 code

Well, the app is actually a Tapestry 5 app... so maybe there is an issue with serialization. I will check. However, a few lines before, I fetched another entity without any trouble. Now, the DataContext is an attribute of a class I instantiate from a Tapestry page. The DataContext is simply c

I see Andrus already replied a bit ... One thing I'd suggest doing when you go back and re-work it is to not do: Expression q = Expression.fromString("patientPk = '" + pk + "'"); This could cause you problems if your string value ever has single quotes in it or other special characters. I
