## Revision 1.18 2003/04/18 15:27:06 joko |
| 30 |
## NEW: XML Trees in data area |
| 31 |
## new ecom module: DataTree |
| 32 |
## introduced new query argument: 'filter' (purpose: xml/tree filtering) |
| 33 |
## $filter = array( |
| 34 |
## dotted => $val['ecom_data_filter'], |
| 35 |
## ident => $val['ecom_data_ident'], |
| 36 |
## ); |
| 37 |
## A Data::Lift module translates this filter-query into a XPath-query ... |
| 38 |
## $filter = array( |
| 39 |
## xpq => '*\/*[@name="cli"]', |
| 40 |
## ); |
| 41 |
## ... which finally is propagated to the backend. |
| 42 |
## NEW: AbstractExplorer - standalone version |
| 43 |
## enhanced set_e_state: now can overwrite internal state to arguments from outside |
| 44 |
## enhanced get_com: also capable of propagating additional args through _load_ecom to _prepare_component_args |
| 45 |
## enhanced _prepare_component_args: now able to dispatch to a "transparent navigation ecom" (e.g. YAA::JobGroups) |
| 46 |
## MISC: |
| 47 |
## added some pre-flight checks throughout the module, especially at the core dispatcher inside _prepare_component_args |
| 48 |
## error checking: added some more croaks via 'user_error' |
| 49 |
