Hello,
For ENI, the source of all the data displayed in ENI is LQE. If an artifact or its attribute is not passed in the TRS feed of an application to LQE, then LQE would not have those information and hence ENI will also not be able to display/use those information.
The RMM TRS feed (Architecture Element shape) does not have any property/attribute related to an associated diagram image; Hence, ENI will not be able to load/display the desired Diagram in the View’s container.
Request you to please create a new idea for this expected use-case in ENI. The link for creating the idea is IBM Ideas.
Thanks!
