[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-28) Upgrade Designer's connection framework to latest GEF behavior

Upgrade Designer's connection framework to latest GEF behavior -------------------------------------------------------------- Key: TEIIDDES-28 URL: https://issues.jboss.org/browse/TEIIDDES-28 Project: Teiid Designer Issue Type: Bug Components: Diagrams Affects Versions: 6.0.0 Reporter: Barry LaFond Fix For: Future Original Estimate: 1 week Remaining Estimate: 1 week Eclipse's GEF AbstractGraphicalEditPart.addTargetConnection() & addSourceConnection() were changed since Eclipse 3.1.2 timeframe to include calls to remove the connection if it already exists. Initial/temp fix was to override these latest methods in AbstractDefaultEditPart to revert to 3.1.2 GEF code. We need to investigate and adapt to the new/changed GEF connection framework and behavior
