"Loading content" problem when unselecting all concepts #69

Closed mniepert closed 10 years ago

mniepert commented 11 years ago

I type something and then unselect all filters; it hangs with "loading content". E.g., type “thea” and then unclick “inpho:entity” and all other concepts.

Reported by Cameron.

I refactored the content explorer and the initial problem should be fixed.

However, the server (at least osdorp) seems to have performance issues if we send to many query simultaneously as we get many socket timeout exceptions. This is kind of strange because everything runs relatively good on my notebook which is relatively old and slow...

mniepert commented 10 years ago

The weird thing is that this only happens for "object properties" and it happens even if only one single value is added. The problem is probably rooted in the query which is specific for object properties.

Is your commend related to this ticket?

If yes: Can you provide an example? I am pretty sure that the query is not the problem as the described problem does not occur on my PC or Notebook. We get a lot of timeouts if we send too many complex queries to our local sparql endpoint (owlim).

Sorry wrong ticket...

jakob0910 commented 10 years ago

Ok, but what's your opinion on this one? There are two possible solutions as it is very unlikey that we get better hardware:

  1. We accept the problem.
  2. After a user select/unselects a type he has to wait until the result is returned before another type can be selected/unselected.

I think for now (1.) is OK. However, note that this is related to #72 . At the moment, the message

"There are no concepts which match the query."

is displayed correctly after a while but the "loading content" for the entities remains indefinitely.

Tickets #71, #72 are already fixed. I will close these tickets tomorrow after we updated the server.

Nice.
