[laverman]

Prerequisites

• Start a new Vorto IDE (either build from git-development, or via update-site).
• Create a new Workspace
• Create new Models (FBs, IMs)

Actions Taken

• Right-click on FB or IM and click on Generate Code

Expected Result

After doing some research it appears to me that in the Workspace folder the following file:
workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
incomplete is. When copying this file from an older workspace, it works.
