E091 Attribute Of Type Not Found Constraint
Umple semantic error raised when a class does not contain the required attribute of a given type
Model constraints can be applied to Umple classes to ensure they respect certain properties, as defined in their constraints. This error is raised if a class does not contain an attribute of a specified type in the constraint.
Example
//The error is raised, A does
//not contain an attribute of
//type B
class A {
[model: A has attribute of B]
}
class B {
}

Solution to The Above So the Message No Longer Appears
//A now contains an
//attribute of type B
class A {
B attr;
[model: A has attribute of B]
}
class B {
}
