I have a strange problem and I don't know why my transformation behaves
like this. So I try to post here all which is important and hope someone
can help me. As I don't know where the issue comes from I attached some
files (model instance and blackbox library).
I implemented a blackbox library which does some computations for a
specified model and then generates a new element which will be added to
the same input model. In my metamodel I defined components which can
have type references. For those type references I will generate a data
channel. For the type references a list will be created. After this
every element in the list will be checked and if it is valid it will be
added to the input model. But after the iteration (method
generateCommunicationModel) the typereferences of the events get null.
The references simply disappear. The strange thing is that the type
references won't disappear from the operations. Example:
before transformation:
<component xsi:type="ccm:ServiceAccessComponent"
name="InternalBuildingsProvider"
descriptionLocation="localhost:8080/BuildingsService?wsdl">
<operation name="collectBuildings"/>
<event xsi:type="ccm:Event" name="getBuildings">
<typeReference
complexType="//@model.0/@dataTypes/@dataType[name='BuildingList'] "/>
</event>
</component>
after transformation:
<component xsi:type="ccm:ServiceAccessComponent"
name="InternalBuildingsProvider"
descriptionLocation="localhost:8080/BuildingsService?wsdl">
<operation name="collectBuildings"/>
<event xsi:type="ccm:Event" name="getBuildings"/>
</component>
And I don't know why the type reference will be removed. Maybe someone
can look over my code and tell me. I'm very desperate.
best regards,
Gilbert

Originally posted by: formatzeh.gmx.de
I discovered something. I have the following method:
private void generatePublishers(EList<Component> components) {
for (Component component : components) {
EList<IEvent> events = component.getEvent();
for (IEvent event : events) {
EList<TypeReference> types = event.getTypeReference();
if(!types.isEmpty()){
if(!containsTypes(types)){
DataChannel channel = FACTORY.createDataChannel();
channel.getTypeReference().addAll(types);
createAndAddDataPublisher(channel, (Event) event);
dataChannels.put(types, channel);
} else {
DataChannel channel = getPublishSubscribeSets(types);
createAndAddDataPublisher(channel, (Event) event);
}
}
}
}
}
With the method containsTypes(types) a map will be searched for existing
keys already containing the types. If such a key doesn't exist then a
new entry will be added. But I discovered that the following line makes
me desperate:
channel.getTypeReference().addAll(types);
In debug mode I found out that after this line the "types" will be added
correctly with addAll but all places where that EList<TypeReference> is
referenced will remain empty. That means that all references will be
null. That's why the types will be deleted where they came from and at
all places where they are referenced.
Is something wrong with the addAll method? Or lies the problem in my
metamodel?
