Unable to add View

[kapcus]

When I want to add View object into erm file, I am getting following exception. Tested with Eclipse Photon Release (4.8) and Eclipse Luna (4.4.1) . I just created blank ERM file, put View Object and tried to save it -> exception. When I fill everything (columns, name, SQL content), exception is raised also. Tried to play with it for a while, but no workaround found. Tested for db Oracle and PostgreSql.

Thx for suggestion/fix.

Exception from Eclipse console:
