[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-2189) Add ModelType validation in the New MED wizard to prevent creating MED without one selected

Add ModelType validation in the New MED wizard to prevent creating MED without one selected ------------------------------------------------------------------------------------------- Key: TEIIDDES-2189 URL: https://issues.jboss.org/browse/TEIIDDES-2189 Project: Teiid Designer Issue Type: Enhancement Components: Extension Framework Affects Versions: 8.3.2 Reporter: Barry LaFond Fix For: 8.5, 8.3.4 The New MED wizard's 2nd page allows selecting View Model and/or Source Model types. However, if neither is selected, then the MED is created without one and can be confusing and will prevent actually defining MED properties. Need to add ERROR message and prevent FINISH if this happens.
