Animation target not specified

[Brian Sayatovic]

My QA testers were able to trigger an error I can't account for that ended up with an 'Animation target not specified' InvalidOperationException thrown from deep within the RadBusyIndicator's animation:

 Message=Exception has been thrown by the target of an invocation.

  StackTrace:

We're using the Windows 8 theme.  From what I can tell the SetPropertiesAccordingIsBusy method is attempting to start the "Hide" animation.  That animation includes a storyboard that tries to fade the visibility of the nested 'Indicator' grid.  All of that is pretty statically find inside the telerik.windows.controls.xaml.

Is this a bug?  Is there something I could've done to have caused this?

Hello Brian,

We have tried to reproduce the issue in a simple project, but with no luck. So it could be great if you can isolate it in a simple project and send it to us. Also simple steps to reproduce could be helpful.
Nevertheless can you confirm that you are using 2013.1.220 and does it only happens in Widnows8 theme or it could be reproduce with other themes also?

Kind regards,
Georgi
the Telerik team

We're not on 2013.1.  We're on 2012.3.  We will try 2013.1 in our next release as we try not to upgrade third party libraries like this during our QA cycle.  For now, we'll either live with the bug, or remove the nested busy indicator in hopes that we side-step the problem in this one place.

As for making a project which can reproduce it, it will take some time.

[Georgi]

Hello Brian,

We have tested it in a simple application containing nested BusyIndicators with the Q3 2012 assemblies, but still no luck. I am attaching my test project just in case.
So it would be best if you can send us a simple project showing the issue. Please take as long as you need we would be happy to assist you further.

All the best,
Georgi

I've not been able to reproduce it in a standalone project.  Whittling down my own project is effectively impossible as it is over 1M lines.

I've recently seen another similar looking stack trace for a problem testers are encountering with our use of RadBusyIndicator:

----------------END---------------------

Again, this is somewhere in the RadBusyIndicator reacting to a property change notification that leads to its busy state changing and its animation trying to start (or stop? not sure).

Since this is so difficult to reproduce, do you have any suggestions of the best way to track down what may be causing this?  Tweaks to styles?  Diagnostic modes I can turn on? Anything?

P.S. We're using Telerik.Windows.Controls, Version=2013.1.415.1050, Culture=neutral, PublicKeyToken=5803cfa389c90ce7

[kity]

Confirm this happying to me too with version (2013.1.527.10.50), theme dark with circle.

Here is style template that I use

Hello Petar and Brian,

We have created a test application with the Style Petar has provided, but as he said it is a rare issue and were not able to reproduce it. Also we have prepared a test that changes IsBusy in different scenarios and we have run it 100 times, but still no luck of reproducing it.
So Brian you can try similar approach - if you know some set of steps that could reproduce it - record it to a UI test and repeat it few times.
Also Brian do you have a custom theme applied to the BusyIndicator as this could lead us to the issue?
If so you can try reproducing the issue in a simple application with the custom theme applied.
Any video or steps guiding on how to reproduce the issue would be appricieated.
Hope this would help.

Regards,
Georgi

[Brian Sayatovic]

Let me disclose a little more: another poster in this thread, Kevin Finke, is a colleague of mine.  We're both developers on the same application.  Our limited testing doesn't include memory leak inspection.  However, our QA team does include such a testing phase and they report back to us their findings.  The screenshot I included earlier today is from their findings.

When I started researching this leak, I stumbled upon this thread, only to find that my colleague, Kevin, had been trying to address this same issue a couple of months ago.  Before that last attempt, we were using Telerik's stock Windows 8 them.  Based on the earlier information in this thread, Kevin put in place an overridden style (<Style TargetType="telerik:RadProgressBar" x:Key="ProgressBarStyle">) with the easing functions commented out (based on your code you provided in this thread).  Today I verified that that "fixed" style is in fact the one being applied to the RadBusyIndicator instance we see in our leaks.  I had actually hoped I would find that we were somehow not applying the fixed style, but that wasn't the case.

I digressed.  So our testers are testing the application as a whole.  My own attempts to reproduce it are rarely successful.  So it is very hard to isolate this problem even on my end.  I don't expect a cleanroom, sandboxed test solution to reproduce the problem will cause whatever complex situation that leads to this.  I can try, but not today.

Have you guys reached out to the other posters in this thread to see if their problems went away with the one-off fix in this thread?

Has your engineering team continued to investigate other possible causes?

If it would help, I could look into sharing our recorded ANTS Memory Profiler session with this leak in it with you guys.

[kity]

In our project we use the same theme (Windows 8) like Brian's  project.

For some reason we change some controls to use custom style. At this case "RadBusyIndicator" use "Dark theme (with circle)". Our tester at this point can not find this bug ;). One of my colleges in debug mode find this error and show me. I do not have time now, because different work priority but when I find free time I will make test programs and I will send to you or will make video at least.

[Mark]

I'm just trying to (hopefully) provide a bit of relief.  I had a similar issue with the RadComboBox and was able to create a sample for Telerik to reproduce the issue.  They've done so and logged a bug to PITS.
 
Perhaps this is the same monster and the bug needs to be expanded to other controls.

Regards,
Mark

[Georgi]

Hi Guys,

Thanks to Mark we were able to reproduce it and we have logged it here in our Public Issue Tracking System.
It seems like the issue Mark has reported and this one are related and both have the same source.
Also changing the theme at run time seems to help reproducing it.  Most likely this is an AnimationManager problem and removing the animation could be used as a work around :
telerik:AnimationManager.IsAnimationEnabled="False".
Hope this would help.

That is great news!  A reproducible bug is a fixable bug!

[Brian Sayatovic]

I tried disabling animation on one of our RadBusyIndicators to see how bad the user experience would feel, but our WIndows 8 theme progress indicator within the busy indicator was still animating (the sliding dots).  Did I disable it properly?

<telerik:RadBusyIndicator
  IsBusy="{Binding BusyState.IsBusy}"
  telerik:AnimationManager.IsAnimationEnabled="False"
  >

[Georgi]

Hi Brian,

Yes, you had disabled the animation properly. Please note that telerik:AnimationManager.IsAnimationEnabled="False" will disable only the animation shown when the BusyIndicator is opened/closed (show/hide) and it will not disable the animation inside of the BusyIndicator. But as it seems like the show/hide animation is causing the issue and disabling it should be enough  in order to workaround it.
If after disabling the animation you are still reproducing the issue, please don't hesitate to write us.

Georgi

[Michael]

Just curious if there has been any update on this.  I am seeing a similar issue when I put a RadBusyIndicator inside the footer of a RadDataBoundListBox

[Georgi]

Hi Michael,

We have performed detailed and extensive research on what could be causing the issue and it turned out that it is caused by a limitation of the Silverlight itself.

So we were not able to fix the issue in our code and therefore we have closed it.

Once again, we are sorry for the inconvenience caused.

Regards,
Georgi
Telerik

 

 

[Brian Sayatovic]

So.... what?  All Silverlight animations are at risk of causing a memory leak because of a bug in Silverlight?  Is it a particular type of animation, or all animations?  Is Telerik going to keep the animations?

I have hundreds of users using our application who are subject to these memory leaks.  If my only option is to ditch Silverlight and Telerik, then I have a massive multi-year re-write staring me in the face.

I'm sorry to be so dramatic, but I'm really worried and I have very little actionable information to go on.  I understand it is not Telerik's fault -- it's MIcrosoft's.  But it's impacting customers trying to use Telerik's products.

[Georgi]

Hi Brian,

I think that there is some misunderstanding as this forum thread is about "System.InvalidOperationException" with message "Animation target not specified." and this is the issues I was referring to in my previous post. Also the issue is hard to reproduce and as a workaround disabling the animation can be used.

Also I have noticed that you talk about memory leak earlier in the post, but i seems like it was intended for another forum post (leak in Windows8 theme) at that time.

If that is the case it would be best if you can open new support ticket where you can share more sensitive information like snapshot form memory profilers like Ants and JustTrace.
