Hi All,
I ve set up AppFuse and am blown away by how neat everything is - Well done
Matt Raible - This is really awesome stuff.
I m seeing an out of memory error when trying to list a 300k table - It
seems to me that the entire dataset is loaded into a hashmap by Hibernate :(
Is this correct? How can I prevent this from taking place?
I ve used AppFuse before and it paginates the data so this is exactly what I
want to happen but I DO NOT want it to get loaded up in a gigantic hashmap
I ve double checked my HashCode implementation but I dont think this is the
problem
Heres the stack trace:
