Selection
A Selection instance allows a ListBox object to browse the data
resulting from a method call such as an SQL Method Call. Selection
instances are used to implement persistent selections in ERP5.
Selection uses the following control variables
- method -- a method which will be used
to select objects
- params -- a dictionnary of parameters to call the
method with
- sort_on -- a dictionnary of parameters to sort
the selection
- uids -- a list of object uids which defines the
selection
- invert_mode -- defines the mode of the selection
if mode is 1, then only show the
ob
- list_url -- the URL to go back to list mode
- checked_uids -- a list of uids checked
- domain_path -- the path to the root of the selection tree
- domain_list -- the relative path of the current selected domain
XXX this will have to be updated for cartesion product
- report_path -- the report path
- report_list -- list of open report nodes
