jbe/bsw@0 | 7 Same as param.get(...), but operates on a special id parameter. An id is set via a __webmcp_id GET or POST parameter or an 'id' option to execute.view{...} or execute.action{...}. In a normal setup a beauty URL of the form http://www.example.com/example-application/example-module/example-view/<id>.html will cause the id to be set. |
