SWEA Hangs on (non-standard) AJAX progress panel

[Ian]

Hi,

After some issues using the default Microsoft AJAX progress indicator
(not being able to click buttons under it even when it is not
displayed) I found an improved version on the internet

http://aspnetresources.com/blog/always_centered_ajax_progress_indicator.aspx

which actually works, and also is always centered on the screen so you
always see it.

It works great with no apparent errors or problems when manually
accessing the web site.

However our automated SWEA tests run via CruiseControl.NET are
randomly failing/hanging.

Running the test suite manually using the Visual Studio debugger it
appears to be either timing out on a WaitForActive or just hanging on
trying to retrieve the value/content of a control.

When debugging and it is either timing out or hanging, IE becomes
unresponsive and when debugging is stopped IE comes back to life.

I know that this improved progress indicator does some clever things
with webresources to deliver it's css and javascript content.

Is this too complicated for SWEA to manage?
Is there anything else I can tell you to help diagnose this problem?

We are using SWEA version 2.0.2.2

Hi Ian,

To troubleshoot the scene activation problems you can subscribe to Error
event of ExplorerManager. The error message contains full identification
log. You can also subscribe to SceneActivated and SceneDeactivated events to
monitor a scene state transitions. You can also use SWEA HttpLog. The SWEA
HttpLog logs all http downloads and "complete" events.

The SWEA scene identification is triggered by IE complete events. In the
case of AJAX IE doesn't fire any events. SWEA is able to simulate the
complete events for AJAX. Do you check the "Detect AJAX" in project
settings? In some cases the "Detect AJAX" may not work - too much "noise"
(too nmany network calls). In this case it is possible to manually run the
scene identification (Uncheck "Detect AJAX" and "Detect DOM Changes"):

If (!scene.WaitForActive(20000))
{
explorerManager.RunIdentification();
if (!scene.WaitForActive(20000))
throw new IdentificationException();
}

Is it possible to reproduce the problem? I have run
CenteredProgressIndicator example, but I was not able to reproduce the
problem.

Best Regards,

We had "Detect AJAX" checked but not "Detect DOM Changes".

I checked "Detect DOM Changes" and tried and also tried it without
either checked and we still had failures.

Below are the exception messages:

From the traces I can say that the Internet Explorer instance was closed when the call to GetWebBrowser windows was done. Have you tried to place a short Sleep statement before DisconnectAndClose? It could be  possible that IE is closed from javascript.
 
Unfortunately I am not able to reproduce the problem. Do you have any example which reproduces the problem?

Hi,

Internet Explorer is definitely not closed as we end up with loads of
orphaned Internet Explorer processes hanging around.

Unfortunately we've removed this panel at the moment to get a release
out so I can't try anything at the moment.

It's a complex page with some custom controls and a treeview from
telerik (http://www.telerik.com/products/aspnet/controls/treeview/
overview.aspx) all wrapped up in an update panel so creating an
example would be problematic.

I suspect that if I just had a page with this update panel then it
would work fine.

Is there any other debugging info that I can provide when we try
adding this update panel back in?

Hi Ian,

Is the orphaned Internet Explorer process visible? When IE instance
closes it notifies SWExplorerAutomationClient. It may be the case when
IE closes without the notification (some internal crash). It may
explain why DisconnectAndClose failed. Do you use any third party
Internet Explorer add-ons? It could be better to switch them off. As a
temporary workaround you can try killing the orphaned Internet
Explorer process using explorerManager.ProcessId.
