Osate reports incomplete end-to-end flow instance and missing connection instance despite the connections existing. #653

Closed TimeWarDoctor closed 8 years ago

TimeWarDoctor commented 8 years ago

The error states: Incomplete end-to-end flow instance [Flow name]:Missing connection instance to [subcomponent] or Incomplete end-to-end flow instance [Flow name]:Missing connection instance to [connection1 name]

However, the subcomponent model has a complete flow specification, and the connection1 exists in the subcomponent.

Hence I am still able to do a flow latency analysis.

Flow instantiation bugs are almost impossible to track down without a model. Can you provide the model you're trying to instantiate?

TimeWarDoctor commented 8 years ago

The models are all in this zip archive attached. I think I did the models correctly but if not please tell me exactly what I did wrong.

Unfortunately, it won't let me attach the zip file...I'll put the text in the following comment instead.

OK...here it is...but remove the .txt upon download.

In the contingency this is a problem with my model, please let me know what I did wrong so I may improve.

It's a problem in the model. You have a flow source specification InformationSystem.HTTPPushFlow_Start you need to add a flow source implementation for that in Type_InformationSystemForPushFlows.InfoSystem. This implementation must include the connection DataPush_FromSystemToNetwork. As is the flow instantiation searches for a connection instance that starts at Type_InformationSystemForPushFlows.Data_Out, which is the port listed in the flow source. However, the connection instance really starts inside at a nested subcomponent.
