Re: [dspace-tech] NullPointerException when visualizing an item

2018-04-13 Thread Gustavo Tonini 
Thank you, Miika.
Worked around the problem by moving the item to the collection where it was 
supposed to be.

Hello,

if I read the code correctly, the NullPointerException seems to occur 
while retrieving the handle of the parent DSpace object (i.e. the 
collection that 123456789/77186 is supposed to be in) before generating 
the Browse->This Collection links.


Perhaps there is some problem in the database - either with connecting 
the collection to item, or with the handle of the parent collection.

Re: [dspace-tech] NullPointerException when visualizing an item

2018-04-10 Thread Tim Donohue 
Hi Gustavo,

A NullPointerException in Java is a generic error that could have many
different causes. So, we'd need more information about where this error is
occurring. If you need help finding the error stack in your logs, please
see this guide:

https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error

Please be sure to post the error stack to this mailing list, and hopefully
someone on this list will be able to more easily help you.

Tim
