Vladimir Glazounov 0af8c282d5 INTEGRATION: CWS pbrwuno (1.3.38); FILE MERGED
2005/10/25 07:13:08 fs 1.3.38.4: #i53095# knitting lose ends (amongst others, make the handlers available as service)
2005/10/17 13:18:58 fs 1.3.38.3: #i53095# proper listener administration: allow multiple listeners per handler
2005/10/05 06:54:04 fs 1.3.38.2: RESYNC: (1.3-1.4); FILE MERGED
2005/08/09 13:59:57 fs 1.3.38.1: #i53095# phase 1:
- don't use strings to transver values between controls and introspectee, but Anys
- first version of a dedicated property handler for form-component-related properties
  (not yet completed)
known regressions over previous phase:
- handlers for events not yet implemented, thus some assertions
- click handlers for form-component-related properties do not yet work,
  thus the browse buttons mostly do not work
