Ivo Hinkelmann be03d183d6 INTEGRATION: CWS dba24c (1.3.110); FILE MERGED 
2007/10/30 08:51:34 fs 1.3.110.3: #i10000#
2007/10/26 12:16:11 fs 1.3.110.2: getImage -> getImages, this saves one call and all its implementation, since all clients did two calls, anyway
2007/10/26 11:55:15 fs 1.3.110.1: #i73245# don't create the Table object to examine whether it's a view, instead ask the Views container supplied by the XViewsSupplier. This saves us O(n) getTables calls, with n being the number of tables
