Can't get EntityManager sometimes!
Hi,
For some reason EntityManager is perhaps unable to initialise sometimes and is able to other times e.g. the interface loads data into a table which of course requires pulling data out of the database and on click of a row in that table I try to re-render items in a drop-down where label of each being one of object's field. The data seems to be there when I debug but it just doesn't show up throwing up following exception (part of the stacktrace). Help/Guidance would be much appreciated.
Thanks
