Jason,

Can you be more specific when you say this bug report is incomplete, i.e.
what additional information you require?

Title:
  Deleting Data Elements in UI very slow / hanging

Status in DHIS:
  Incomplete

Bug description:
  I have observed this behaviour multiple times now (2.18 and 2.19:

  When deleting data elements from the data element list, the process is
  unreasonably slow (2-8 minutes) on a relatively slow connection (in
  this case I'm using a basic 1mbits connection in Norway running into a
  Cape Town server) AND in most cases the "progress bar message"
  DELETING..... is never replaced by the "Object deleted" message.

  When deleting similar data elements from a local instance, it takes
  around 15 seconds. This is also relatively slow, in particular since
  the most demanding lookup into the datavalue table only takes around 1
  second running as a separate pgSQL query - which leads me to suspect
  that there is some inefficient code (nested query or similar) in the
  delete DE sequence.

  With a slow connection, it seems like the DE delete sequence takes so
  long that some kind of time-out takes place.

  In some cases, refreshing the browser page will show that the deleted
  DE is gone - in other cases the browser (cache) still shows the DE is
  there, whereas  checking the server instance via pgremote shows the DE
  has indeed been deleted. If the refresh button is hit too early - let
  us say within 1-2 minutes - there's no change in the database.

  Note that I have only observed this low performance / tendency to
  "hang" when deleting Data Elements - all other deletions seems to be
  quick.
