Hi,
this really bugs me since two days and I'm really out of my depths here. In my app I have a WebButton whose action does a simple self redirectToView: .... like I have in several cases. This is the generated HTML, both buttons have the same problem. <inputtype="submit"value="Dieses Profil drucken"name="plotThis"> <inputtype="submit"value="Alle Positionen drucken"name="plotAll"> <td> This always works on a Windows Server and on an Ubuntu Server running in a VM in my local network. On the hosted Ubuntu server (same Ubunu) only on Firefox it regularly fails (not always) while it always works on Chrome and Opera. The tendency is: the slower the computer running the browser the better it works. The problem is that the action method of the button never gets sent, because SwazooBuffer>>refillFrom raises a SwazooStreamNoDataError "No data available, socket probably closed". I get the same problem with several versions of Swazoo incl. the latest download from Aidaweb.si. I've attached a Stack trace. Help is really appreciated. Thanks, Herbert _______________________________________________ Aida mailing list [hidden email] http://lists.aidaweb.si/mailman/listinfo/aida |

One upon the time Squeak Swazoo had some such problems and can be related to your problem. > > I get the same problem with several versions of Swazoo incl. the latest > download from Aidaweb.si. > > I've attached a Stack trace.

Hi Janko,
Am 13.11.2012 23:29, schrieb Janko Mivšek: thanks a lot. Shall I use Wireshark on the server (text only) or on the client? Anyway, important things first, so I replaced the buttons with links which works and I wrote a Selenium test which tests this several times and ran it on three computers simultaneously for an hour. Not a single failure. As tedious as it is to write a Selenium test for a dynamic webapp as big is the confidence you get out of them. BTW the Hetzner Vserver performs well, around 10% user CPU from top. So the pressure is away and tonight I'll check what you suggested. Because before I tried to put these buttons elsewhere and could not get rid of the problem.
