[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-2896) Unhandled event loop exception in the specific situations

Unhandled event loop exception in the specific situations --------------------------------------------------------- Key: TEIIDDES-2896 URL: https://issues.jboss.org/browse/TEIIDDES-2896 Project: Teiid Designer Issue Type: Bug Components: Dialogs, Eclipse Integration Affects Versions: 10.0.1 Reporter: Matej Kralik Labels: release_notes, verified_jbdsis-9.0.3 Fix For: 10.0.2 Attachments: screenshot1.png, screenshot2.png In the specific situation (when I want preview data without a server or add properties to unselected model in the VDB editor) teiid designer does nothing and in the error log is "Unhandled event loop exception". In my opinion, the button (preview data or add new Property) should be disappeared in this situation or teiid designer should show some alert (the server has not been added, the model has not been selected).
