We have had multiple PMRs on 18.104.22.168 regarding process model corruption caused by the usage of Map node. The issue was fixed and released with V22.214.171.124 Interim Fix 1. Please move to V126.96.36.199 Interim Fix 1 as soon as possible if you need to use maps in your models.
Not moving to this Version would result in loosing the work done during modeling and it is not always possible to recover the models.
In order to use the map nodes in a process model, upgrade to at least WebSphere Business Modeler Version 188.8.131.52 Interim Fix 1.
IBM WebSphere Business Modeler Advanced V184.108.40.206 Interim Fix 1
If you insist on staying on WebSphere Business Modeler 220.127.116.11, then when updating a process that contains map nodes, the map editors should not be opened. If you happen to open the map editors, then you should do the following:
- Close all map editors.
- Close the process editor WITHOUT SAVING.
- Open the process editor. DO NOT OPEN THE MAP EDITORS.
- Continue editing.
When updating a process that contains a map node, you should keep the map editor closed. This will prevent the process model from getting corrupted. Otherwise please upgrade to at least WebSphere Business Modeler Version 18.104.22.168 Interim Fix 1.
