我想将为UML-Property定义的构造型应用于关联中使用的属性。我遇到的问题是在对关联关联属性使用构造型的情况下抛出IllegalArgumentException。如果我将构造型应用于在类中使用的属性作为属性，一切都很好。

以下是异常抛出部分的代码片段：

helper def: getStereotype(name: String): UML!Stereotype =
UML!Stereotype.allInstancesFrom('PRO') -> select(p | p.name = name) -> first();
-- ...
p1: UML!Property(

    upper <-a.associationEnds.first().conformance.upperBound,
    lower <- a.associationEnds.first().conformance.lowerBound,
    name <- a.associationEnds.first().name,
    type <- firstMemberType,
    opposite <- p2,
    isComposite <- true
),

p2: UML!Property(

        upper <-a.associationEnds.last().conformance.upperBound,
        lower <- a.associationEnds.last().conformance.lowerBound,
        name <- a.associationEnds.last().name,
        type <- secondMemberType,
        opposite <- p1
    ),

as:UML!Association(
        name <- a.name,
        ownedEnd <- Set{p2}
        navigableOwnedEnd <- Set{p1}
        )
    do {
p1.applyStereotype(thisModule.getStereotype('xsdElement')); -- here an exception is thrown: see below
}

抛出以下IllegalArgumentException。

Here appear some other resulting stacktraces.

我使用了UML=http://www.eclipse.org/uml2/3.0.0/UML。

似乎p1不再是属性了。有人有想法吗？会很好。谢谢，马丁

EDIT1：

在做了一些调试之后，我发现流中方法的调用是第一次成功。在调用方法finalizeModel之前，everthing很好。当调用ATL UML2ModelAdapter中的方法finalizeModel时，抛出堆栈跟踪：

我已经解决了我的问题。

问题是，我已将配置文件应用于从属包而不是根包。我已将关联添加到根包中。因此，每次尝试将构造型应用于root-package都失败了，因为它对我的个人资料一无所知。

因此，当属性是关联的一部分时，属性关联的构造型的应用程序才会崩溃。表示类属性的属性位于从属包中。

将构造型作为关联结束应用于属性会抛出IllegalArgumentException
