7    ##    Revision 1.20  2003/04/19 16:24:49  jonen
8    ##    + added two more GUI modules to default registry initiation,
9    ##       relating to new navigation module 'NavigationTree'
10    ##    + added prepartion of needed args for abstract navigation tree
11    ##       and concret UserManagment 'UMnav' tree
12    ##
13    ##    Revision 1.19  2003/04/18 16:21:37  joko
14    ##    fixed commit comment - the last one caused a syntax error!!!
15    ##
16    ##    Revision 1.18  2003/04/18 15:27:06  joko
17    ##    NEW: XML Trees in data area
18    ##      new ecom module: DataTree
19    ##      introduced new query argument: 'filter' (purpose: xml/tree filtering)
20    ##        $filter = array(
21    ##          dotted => $val['ecom_data_filter'],
22    ##          ident => $val['ecom_data_ident'],
23    ##        );
24    ##        A Data::Lift module translates this filter-query into a XPath-query ...
25    ##        $filter = array(
26    ##          xpq => '*\/*[@name="cli"]',
27    ##        );
28    ##        ... which finally is propagated to the backend.
29    ##    NEW: AbstractExplorer - standalone version
30    ##      enhanced set_e_state: now can overwrite internal state to arguments from outside
31    ##      enhanced get_com: also capable of propagating additional args through _load_ecom to _prepare_component_args
32    ##      enhanced _prepare_component_args: now able to dispatch to a "transparent navigation ecom" (e.g. YAA::JobGroups)
33    ##    MISC:
34    ##      added some pre-flight checks throughout the module, especially at the core dispatcher inside _prepare_component_args
35    ##      error checking: added some more croaks via 'user_error'
36    ##      cosmetic updates
37    ##
38    ##    Revision 1.17  2003/04/18 13:46:15  jonen
39    ##    + add hidden elements(items) now to the constructor arguments of each ecom
40    ##
41    ##    Revision 1.16  2003/04/10 06:00:58  joko
42    ##    ALPHA: Item.Delete
