eMoflon IBeX FAQ

Welcome to the eMoflon::IBeX FAQ!

Here we collect common problems that may occur while working with or developing eMoflon::IBeX:

---

Problem: The eMoflon perspective can't be opened.

• Possible solution: Install and use Java JDK >=17 to run Eclipse/eMoflon.

---

Problem: The eMoflon test workspace compiles just fine but the execution fails with an error like "some file xy could not be found".

• Possible solution: Use CTRL+A in the project explorer and hit F5 multiple times until ~100k warnings are found. (Apparently, the Eclipse caching mechanism fails quite often ...)

---

Problem: The saving of a model fails with some unreferenced objects.

• Possible solution: Make sure that each entity of your metamodel is contained precisely once.

---

Problem: Some fubar with model attributes (int, float, double, ...) happens.

• Possible solution: Do not use upper and lower bounds for number attributes. Only use them for, e.g., sets.

---

Problem: Some of the generated code could not be compiled.

• Possible solution: Sometimes, Eclipse does not delete older deleted code properly. Delete all generated code before trying to generate it again (by using the Genmodel file -> right click -> "Generate model code").
