Is it possible in Camunda-BPM to trigger an Error Event, which is attached to a User Task?
What I got looks something like this:
According to BPMN 2.0.2 there are no restrictions on using an attached Error Event on a User Task, but I ddnt find any solution to this problem so far.

I wonder if someone can help me with getting my PDF download event to show up as a conversion? I have read other posts on here and also asked on the Google forum but so far I haven't managed to get it going. Please note, I am using the new, universal tracking code.
What I have done so far:
Set up in Google Tag Manager event tracking - this works perfectly and is recording in GA.
I have added the code to the PDF link that I am trying to track anchor text
Set up Goal in GA with event type set to Event with the fields set to 'equal to', except for value which is marked 'greater than'. Category - PDF, Action - Download, Label - Brochure, Value - 250.
What am I doing wrong? Nothing comes up when I verify this goal and nothing comes up in real time conversion tracking.
Thanks in advance.

You might have an error with your Google Analytics event configuration. Try this:
Remove the goal Value in the Goal Details (Event Conditions)
Change to NO "Use the Event value as the Goal value for the
conversion"
Set the value yourself (e.g. 5$)
Make your to remove the value from the GA javascript or Tag in GTM
I have two page application and the main page is default is "MainPage.xaml" and the second one is "AddPerson.xaml" when user click a button on main page I want the app to take user to "AddPerson" page.
And I wrote following for the Click event of the button
Me.Frame.Navigate(System.Type.GetType("AddPerson.xaml"))
and I am getting the following error
An exception of type 'System.NullReferenceException' occurred in MedicineSchedule.exe but was not handled in user code
Additional information: Object reference not set to an instance of an object.
If there is a handler for this exception, the program may be safely continued.
I tried other method of navigationservice.navigate which I cannot find the class in VS2013 express at all. The only method available is Me.Frame.Navigate in my project, please let me know how I can get this simple thing to work.
If it was .net 2.0 I would simple called new form with form.lod or something similar.
This doesn't work?
this.Frame.Navigate(typeof(AddPerson));
If you want/have to use a string take a look at the reply here:

I am using Wix Burn to install per-requisites of our project, I have used ManagedBootstrapperApplicationHost to have custom UI, I have been following project available from Wix Source code to create my Managed WPF application..
Now the problem is the Progress (Message) it shows that doesn't match the progress message we have using inbuilt UI - WixStandardBootstrapperApplication.RtfLicense
Basically I am using following code from the Wix source
private void ExecuteMsiMessage(object sender, ExecuteMsiMessageEventArgs e)
{
lock (this)
{
this.Message = e.Message;
e.Result = this.root.Canceled ? Result.Cancel : Result.Ok;
}
}
How can I have the same display as the normal Progress dialog has.. Do I have to individually set Message from other methods like PlanPackage etc..
The wixstdba does not show the action data progress messages today. There was someone talking about adding the feature on the wix-devs mailing list but that has not happened yet. It's simply a matter of adding code like you have in the managed case to the wixstdba (that doesn't have it yet).
If you just want to display the name of the package being installed the way the wixstdba does it, then you'll want to handle the Engine.OnCachePackageBegin() and Engine.ExecutePackageBegin() callbacks. Those callbacks tell you when a package begins to be downloaded and then installed respectively. As part of the args to those callbacks you'll be provided the package id.
To get the friendly display name, you can read the BootstrapperApplicationData.xml that is automatically included next to your Bootstrapper Application .dll. In there are WixPackageProperties elements that provide lots of information about the packages in the bundle, including the DisplayName.
--- Sorry, the following is an answer to a question that wasn't asked. ---
The Engine.ExecuteMsiMessage() callback is called when the Windows Installer displays a message (like action data or a request to prompt the user for input). Progress is provided via a three different callbacks.
You can get the overall progress via the Engine.Progress callback. This is a very coarse grained progress that essentially moves as each package is cached and executed.
You can get the overall and individual package progress via the Engine.CacheAcquireProgress. This progress moves as each package is downloaded/copied and verified to be placed in the Package Cache.
You can get the overall and individual package progress via the Engine.ExecuteProgress callback. This progress moves as each package is installed/repaired/uninstalled.
So the Engine.Progress shows you the total overall progress and is very easy to use for a single progress bar but the progress bar will not move very smoothly. You can get a smoother overall progress by adding the Engine.CacheAcquireProgress to the Engine.ExecuteProgress. Note: that will give you a progress bar that goes to 200.
You can see how the WixBA handles all this in the src\Setup\WixBA\ProgressViewModel.cs file.
I'm writing a small custom player based on libvlc. I've used much of the code from https://github.com/hartror/python-libvlc-bindings/blob/master/examples/gtkvlc.py that plays a single track just like I need.
Now I want to swtich to another track after previous has finished. To do that I catch callback "EventType.MediaPlayerEndReached" and in callback handler I write code:
<------>def endCallback(self,event):
<------><------>fname = vlc_controller.GetNextTrack()['url']
<------><------>self.w.set_title(fname)
<------><------>self.vlc.player.set_mrl(fname)
<------><------>self.w.set_title('after set_mrl')
<------><------>self.vlc.player.play()
<------><------>self.w.set_title('after play')
Now when this code gets executed it stucks on self.vlc.player.set_mrl(fname) and does not go any further and as a result I see NO NEXT TRACK.
I've tried different variations of this code using (vlc.stop(), vlc.set_media instead of vlc.set_mrl) but nothing works
Finally....
I think the best choise is to make multi threaded application on python
2 Threads:
Main thread - gtk.loop and displaying video an some other thinks
Additional thread that makes media switching.
For some time I was afraid of multithreading but now I know that this was the best way to do this task
For those facing similar issue in C# (Xamarin), per VLC documentation, calling the VLC object from an event tied to the object may freeze the application. So they said to use the code below inside the trigger event.
ThreadPool.QueueUserWorkItem(_ => PlayNext());
An example would be calling the code above inside the EndReach event.
Where PlayNext() is your own custom method to handle the next action you want to execute.
I struggled with this for about a day before seeing that portion of the documentation.
I have a question about the BPMN notation. Does anybody know if interrupting/non-interrumpting events can be for throwing and catching. The specification (v2.0) doesn't define this explicitly (or maybe I missed it) but it seems it only defines the icon for catching the event.
Maybe I am misunderstanding the use that events attached to the border of an activity have.
If I had to take a guess I would say that it is only catching since events attached to the border of an activity are catching things that happen inside subprocesses or activities. Things that happen outside the scope of the activity or subprocess do not influence what can happen inside it.
Thanks for your help.
interrupting (int) /non-interrumpting (n-int) are only catching events. they can be used in sub-processes and as boundary events.
the diffrence between int and n-int as a boundary event is:
- [int] when fired the action is blocked
- [n-int] the event is fired but the action still goes on.
here you can see a simple doc with all the grammar. if you look on the right side you can see that no trowing can be (n-int).
if you think about that, trowing event does not have to wait for do their action, so n-int or int does not make any sense.
