    Apex listener 2 error "Returning:oracle.dbtools.common.util.Closeables$1@"

    Damir Vadas
      Hi
      Problem is that page is blank and freezed. After another enter in URL page is shown normally.
      What I find out is that "freeze" happened only in Apex design time ... never in runtime of any of mine app.
      Mine conf:
      Apex 4.2.1 on

          Hi Damir,
          thank you for your report, can I ask for a few clarifying details:

          You say the page freezes and you have to reload the page again

          - When you say freezes, do you mean the page finishes loading and no content is returned from the server, or do you mean that the page looks like it is still loading (spinner on tab is animating), but nothing is coming back, and eventually you hit the reload button?

          - If it's the former can you use Firebug or Chrome Developer tools to take a dump of what response headers and content are returned by the listener. Also if you view source on the blank page is there any content in it?

            Page is blank ... and loading as you say with spinner in tab

            No probs. You mean to take dump from freezed (blank) page?
            For that I need to play a little more with Apex development. Will do that in incoming days ... and post the result here in this thread

              Page was freezed when switching theme from 11-25.

              This time only freeze appear ... no listener log!

              If I understood you right, here is debugging info that you wanted from me:

                Damir Vadas
                because Apex was freezed again but without any logging in command prompt I have investigate and found out that most of the freeze-ing come from Eset 5.0.2126 antivirus.

                I have asked a question on ESET support (what to do to overcome this) but still have no answer.

                If anyone here do know something (what to disable ... I tried several things as exclude URL filter where apex reside -"http:/IP:port/apex" but no success)

                THX for patience ...
