Possible Error in Papyrus [message #1778596]

Hello, im trying to use Papyrus, but when i draw a simple class diagram like:

1 employee works in one company, and one company has one employee ( 1 to 1 relation).

When i generate the code in Java it appears the company and employee class, but it doesnt appear any reference to employee or company....

What i get ( two files employee.java and company.java):

class employee {
char idemp;
//other attributes
}

class company {
char idcompany;
//other attributes
}

what i expected ( and think should be)
class employee
{
char idemp;
//other attributes
Company cmp;
}

class company {
char idcompany;
//other attributes
Employee emp;
}

Because in one to one relation, you have to assign zero or one value to the other class.
I dont know if its some properties or settings problem

I think that relations with many ( one to many, many to many) its ok, as appears an Array of elements of the class.
ex: one company has many employees
class company {
char idcompany;
//other attributes
Employee[] emp;
}
i think this is ok.

Im using latest Eclipse version with Papyrus form Eclipse Market.

Thanks

Hi,

The generated code is conform to navigability in the UML specification, i.e. if C1 cannot navigate to class C2, then a reference of C2 should not be generated in C1.

When you created the association, are you sure both member ends of the association are navigable? Navigability of member ends can be specified by clicking on the association, and checking its properties in the Properties view. Note that you can directly create navigable associations with the palette of the class diagram, by using the Directed Association tool (or one of the other similar tools in the palette). If the members ends are navigable, they should then be contained in the classes themselves (instead of the association) as UML::Property of the classes. In the diagram, a "dot" should appear on any association member end that is navigable.

Hope this helps.

I solved it changing the owner of the relation, instead of Association to Classifier. I dont understand which is the difference, but setting Navigable to True in both, if the owner is Association it doesnt work and if i put the Classifier as a owner it works.

Also how can i put attributes and operations ? It appears properties and stereotypes, and some are shown in the model explorer and others not.....I just want to set ex: name String salary int in Employee class ( just show them in the rectangle below the class name in attributes). Private visibility

Also write some operations void calculateSalary and getName for example as operations. It would be nice to be shown in the model explorer ( in a rectangle below attributes). Public visibility.

Thanks

Thanks in advance

Hello Eduardo,

If you create a property (or operation) in the model explorer, it may not show up in the element compartment on a diagram.

Have you tried to right-click on the diagram element and selecting "Filters > Show/Hide Contents" in order to show what you need to see?

Alternately, you if you always want to see all the content, you could turn on "Filters > Synchronized with model."
