Bug 1155369

Description of problem:
In general, the guided rule editor requires an unreasonable amount of effort in order to reflect changes to the underlying fact model brought on by a new or updated dependency. 

Judging by the logs, issues seem to be related to the below class or a listener/controller that invokes the class.

Version-Release number of selected component (if applicable):


How reproducible:
Every time - although there is multiple paths.

1) A new version is published to Nexus and BC is configured to use that nexus for snapshots. Reproducing this is described below.
2) Uploading a jar

Steps to Reproduce:
1. Open a guided rule asset in Business Central
2. Build and deploy a new fact model to an artifact in a central nexus.
3. Click build and deploy in Business Central on the project to force the loading of the snapshot to the local maven repo.
4. Return the open guided rule asset. 

Actual results:
Model changes in the new snapshot are not represent

Expected results:
Model changes are represented
