1. A control token is offered to the decision node
   
2. As there are no guards and the offered token is a control token then both outgoing edges are eligible to receive an offer
   
3. An offer is made on the outgoing edge targeting "Open Jira Record"
   
4. This offer is consumed by the activity node and the execution flow propagate through the "Open Jira Recored" outgoing edge
   
5. As the token offered to "Open Jira Record" was consumed, then the offer on the "Solved by Support Team" incoming edge is no longer valid
   
6. As a consequence, "Solved by Support Team" is never ready to fire and the execution terminates
   

1. You can find more explanation regarding the described semantics in the second paragraph of clause 15.3.3.6 in [UML 2.5.1].
   
2. It seems there is no relationship between the execution issue and the problem you describe
   

Hi Carsten,

What do I need to model ? Where should I write the following code in papyrus ?I have uploaded a screenshot.What kind of guard condition do I need to write and Which element in the model ? Thank you very much for your help.There must be a system that works according to a parameter in my model. when I change the parameter, the moka should change on the chosen path. I want to execute "Open Jira Record" and "Solved By Support Team" with Moka. How can I write a condition ?

Cheers

1. A factory: create a object of type Class3, call the constructor and call the classifier behaviour of the class3
   
2. A constructor: which initialize the property1 of the instance of the class3
   
3. The behaviour you want to run: read the parameter1 and take one branch or an other branch according to the property value
   

Hi,

I don't know exactly what your are doing but it seem that there is no value incoming on the DecisionNode. You say that you need to take the decision according to the value of a property you have, so you should put this value as an input of the decision node.

I propose you an example of a working model. In this model, there are 3 diagrams:

1. A factory: create a object of type Class3, call the constructor and call the classifier behaviour of the class3
   
2. A constructor: which initialize the property1 of the instance of the class3
   
3. The behaviour you want to run: read the parameter1 and take one branch or an other branch according to the property value
   

In this example, according to the value given by the ValueSpecificationAction in the constructor , the main behaviour will take one branch or the other.

HTH,
Pauline

Hi Pauline ,

Thank you very much for answering.I run the program but execution is stop in this point. I share a photo.I'm already doing this way decision node.but Moka does not execute.Moka stops when it comes to the decision node.(Moka not execute).I share photo.I use eclipse-jee-oxygen and I use install Moka plug-in in the eclipse installation. Can you tell me which eclipse version and version of Moka? Can you share download links Eclipse and Moka.

Hello,

May I ask you how did you launch Moka ? I provide a launch configuration (you can right click on it -> Run as -> Run_Example), in any case you should make sure that in the debug configuration the Element to be executed is the Example::factory other wise the object is not created and the property is not initialized.

I use the nightly build of Moka [1] but I don't think that makes any differences.

1: https://hudson.eclipse.org/papyrus/view/Moka/job/papyrus-moka-master/lastSuccessfulBuild/artifact/releng/org.eclipse.papyrus.moka.p2/target/repository/

In this example, according to the value given by the ValueSpecificationAction in the constructor , the main behaviour will take one branch or the other.

Hello Pauline,

I run this example .Worked as follows. But Moka choosed false path. How can I run true path ? how can I apply it on my own example ? Can you please help me ? I shared the sample with you.

Hello,

As I said : Quote:

In this example, according to the value given by the ValueSpecificationAction in the constructor , the main behaviour will take one branch or the other.

So in this example to change the used branch, you should change the value of the ValueSpecificationAction in the constructor. An other solution is to use an AddStructuralFeatureValueAction (see clause 16.8.3.3 in [UML 2.5.1]) to change the value of the Property1 of the instance of the Class3.

I am sure this is not exactly what you want to do but I hop it can helps you to adapt it to your use case.

Regards,
Pauline

Hi Pauline ,

Where is the ValueSpecificationAction ? I want to do as in your example . can you help me apply my example please ? I upload my example .
