In a Papyrus Model, I clicked the Use Case Diagram (which is quite simple - contains about 5 use-cases), and selected "Designer -> Generate Java Code".
In response, I got hundreds of new packages, each of which contains hundreds of empty classes, with strange names such as "Aaixixnrpr", "Aclywqwwlr", etc...
What is happening?!
Papyrus SW designer does not have a particular code generation support for "use case" elements, i.e. it will treat an Actor or a Use Case just as a UML class. This means that it will create an empty Java class, unless you add operations/opaque behaviors.
But the Java code generator should not create classes for elements that are not in the model. Can you please double check via the model explorer that elements such as "Aaixixnrpr" do not exist in the model?
Which version are you using? (I recommend to use version 1.0.5 from this update site on an Eclipse oxygen). Btw, I also recommend to use the Papyrus forum for questions like this.

I'm creating a very simple class diagram using the Eclipse Papyrus but I'm not able to represent instances correctly.
First of all, I'm using the SysML 1.6 profile, so my classes are actually represented in a Block Diagram instead of classes, but I believe that this does not change anything in my problem.
After creating a simple class/block in my block definition diagram (bdd) I defined some attributes for my block like the example below:
When I tried to create some instances of my block ("parts" in SysML naming convention) using an "Instance Specification" I'm not able to inherit these attributes and fill them with actual information like the "name" and "quantity" in this example.
It's possible to see that my classifier is correctly set as "My component".
The Papyrus documentation for the Object diagram is clear and says that these Instance Specification should include my attributes so I don't know what I'm doing wrong.
I've tried since now:
Create instances in the same block diagram (bdd);
Create instances in another dedicated diagram of the type internal block definition (ibd);
Use the Papyrus context menu to show/hide all my compartments. Any of them works to show my attributes.
Apparently, the same problem occurs without any SysML profile and using pure UML like this question here (from 2016!!)
Papyrus version: 6.1.0
I am playing with Enterprise Architect for the first time and looking at options for adding Test Cases. I have found a way to add A test case element -
Right-click on element | Properties | Responsibilities > Scenarios > Structured Specification
and this seems to get me where I want quicker as we aren't using Use Case diagrams right now.
While I'm looking at options though I wanted to check, a lot of documentation says, and a Youtube entry shows that you can add a test case from the tool box in a Use Case Diagram. I don't have that option though, in Use Case I just have Actor, Use Case and Boundary. Is this a version thing and it's been deprecated or am I missing a trick ?
Thanks
You can add a test case element from the custom and maintenance toolboxes
Since v14 Sparx has somewhat cleaned up the toolboxes and removed the Test Case (which is not defined in UML) from the UML Use Case toolbox.
We aim to execute fUML specifications written in Papyrus using the fUML reference implementation. This has not been challenging since an UML model containing a single Class diagram and one or more Activity Diagrams can be directly executed by calling the fUML constructor:
new Fuml(File);
However, it is difficult to specify complex behaviors without basic Integer operations. For example, 'equals', 'greater'...
I am aware that there is some library of such functions that can be selected using OpaqueBehaviors. Therefore, my question is: where and how can those such "basic operations" be found?
Sorry, this question was just pointed out to me recently. But, in case you haven't figured it out yet, I do have an answer for you.
The library you are looking for is the Foundational Model Library, which contains packages such as IntegerFunctions, BooleanFunctions, etc. The normative fUML specification includes a standard XMI file for this library (at http://www.omg.org/spec/FUML/20121019/fUML_Library.xmi, for fUML 1.1). However, to use the library in Papyrus, you need an Eclipse .uml version.
If you want, you can convert the normative XMI yourself: Download the file and open it in the Eclipse UML Editor (not Papyrus). Select File > Save As and save the file with a .uml extension (fUML_Library.uml). You should then be able to import this .uml file into Papyrus and reference the functions in it from your activity models. As long as you maintain the normative element IDs from the original XMI file, the reference implementation will know that these are standard library functions, for which it has built-in implementations.
However, there is actually a .uml version of this library already available for Papyrus. It is included with the additional Moka Model Execution component for Papyrus. If you install this component, then the fUML model library becomes available as a "registered library" that you can import into your model and use as above.
Note that Moka also includes an fUML execution engine that you can use to execute activity models directly within Papyrus (see https://wiki.eclipse.org/Papyrus/UserGuide/ModelExecution). However, any models created in Papyrus that can be executed with Moka can also be executed externally from Papyrus using the reference implementation, just as you have done before.
I tried to install the EMF plugin inside eclipse but some of the default Ecore diagram and EMF Generator Model projects were not available.
So downloaded a different eclipse installer for modelling i.e. Eclipse Modeling Tools (275 MB ) and found all the relevant model related & diagram based project now.
I have followed the same tutorial http://www.vogella.com/articles/EclipseEMF/article.html .
I was able to create the webpage model diagram & then the webpage.ecore file but then the webpage.genmodel the model generator file was giving errors like the ” names used in the diagrams for the objects are not well formed ” in webpage model diagram .
I googled for these errors which according to me mean that the names are not proper according to the given language for modeling constraints & no resolution to these errors were found.
then tried to ignore the errors and tried Generating the domain classes for java code, java code is generated but then the other following modules Create your model & Edit your model under Run your plugins category does not work further due to the previous errors on this link http://www.vogella.com/articles/EclipseEMF/article.html.
Please help me debug these errors
check if Name property is not null , you need to fill it
http://emftools.tuxfamily.org/wiki/doku.php?id=emfvb:quickstart
You need to set the name of Epackage and also prefix and URI

I want to create GUI components from XSD files. The generated GUIs should be used for concrete xml instances of the corresponding schema with databinding to "interesting" elements or attributes content.
I have considered these solutions:
jaxfront. (commercial tool). This does not generate source code. This is important for me because I want communication between the generated GUIs and other components of the GUI.
Use xsd2emf and try to generate an editor from that. The generated model is to complex, as well as the generated editor and it is buggy.
Do it myself e.g. generate an xml from the xsd, load xml as dom, select the interessting parts and generate data binding using one method described at http://www.vogella.de/eclipse.html.
Has anyone another idea or already successfully solved that problem? I would prefer a free open source solution which generates a SWT GUI.
Have you looked at the Sapphire framework at eclipse?
With it you have to create a model based on a few simple java interface files with some annotations that would model your XSD. Then once you have the model defined, you create the SWT GUI with a single xml file (sdef file) that wires various property editors to your model. The property editors can be simple widgets like label, text, lists, combo boxes but also it can be complex editors like a GEF-based diagram editor. So basically if you have a few interfaces that describe your model, then can have a graphical editor for editing nodes in that model with less than 100 lines of XML.
