hi everyone,
i am using XPand to generate code from UML to java. i do this using emf as meta-metamodel and the uml-specification as metamodel
(short: i'm using an uml.ecore as metamodel)
now i am trying to have access to the upper and lower multiplicities of properties, but it doesn't work. i tried property.upper, property.upper.toString(),
uppervalue(), upperbound and so on. sometimes i get an exception and sometimes i just get one for upper and lower, although i set another value.
even worse: when i set the upper to * i get this:
org.eclipse.emf.ecore.xmi.IllegalValueException: Value '*' is not legal
i have no idea why this doesn't work, the other things like classes, interfaces, operations, etc. work very well.
every hint is welcome.
best regards,
stoehm

I'm not sure your questions are about Ecore's API... The name of the
bound features of ETypedElement are upperBound and lowerBound.
Unbounded (displayed as *) is represented as the value -1.

hallo ed merks
thank you for your reply!
the problem is, i tried already upperBound (and lowerbBound) but then i get the following exception:

i also looked up in the model file, but there are upper and lower values for example in this attribute:
<ownedAttribute xmi:id="_5F68wIEiEeC9E-8eSOfGQw" name="i">
<type xmi:type="uml:PrimitiveType" href="pathmap://UML_METAMODELS/UML.metamodel.uml#Integer"/>
<upperValue xmi:type="uml:LiteralUnlimitedNatural" xmi:id="_HHuDkIEjEeC9E-8eSOfGQw" value="10"/>
<lowerValue xmi:type="uml:LiteralInteger" xmi:id="_RNO7AIEjEeC9E-8eSOfGQw" value="5"/>
</ownedAttribute>
i get the same problem, when i want to acess the full qualified name!
maybe the problem is another and caused by the metamodel and metametamodel im using!
as i mentioned above as a metamodel i am using an ecore file, which describes the uml. then i am using a model, which is a *.uml file and not a *.xmi file.
(the problem is i have to use *.uml, cause the editor i use just generate files like this, and this is why the upperValue ist * for unbounded even if i type
-1)
i hope now the problem can be found
thanks for help
best regards

so i found now a very easy solution for my problem (i just made things too complicated)
i just did it the same way like in the xpand tutorial about the UML2Example
so i don't need an ecore file which represents the uml-specification, which makes things a lot easier
