Create New Service wizard fails on empty Metadata Model Diagram --------------------------------------------------------------- Key: TEIIDDES-846 URL: https://issues.jboss.org/browse/TEIIDDES-846 Project: Teiid Designer Issue Type: Bug Affects Versions: 7.2 Reporter: Denis Golovin Assignee: Barry LaFond Attachments: screenshot2.png, screenshot3.png, screenshot4.png, screenshot5.png, screenshot6.png There are several options to consider here: 1. Disable New Web Service Wizard for empty diagrams 2. Disable Finish button in Create New Service Wizard and show error message for wizards called on empty diagram I would go with option #2, because it helps in understanding what needs to be done to create Web Service. First option just disable illegal action without saying a word what needs to be done to enable it.
