Did you check line 1675 of HomeDataProvider.java. What is it doing ?

[David Morrison]

Hi, it has stuff of jobs. LIke completing many workflows.

[Paul Beckett]

I don't know of the HomeDataProvider class you have mentioned. Is it part of some internal work done by you or your company?

NullPointerException is very common in development and mostly caused by coding error. You will need to post the relevant chunk of code for anyone to even be able to begin to help. You probably don't need to post the whole class but please indicate which line is 1675.

Really? One single line of code has "stuff of jobs", and is completing "many workflows"? I doubt it.
