Part of the client side editing sub-system is implemented as a 'plugin' for the map view, so the first thing that needs to be done when enabling the editing sub-system is to register the edit plugin with the map view in the client configuration.

When performing an edit a view panel is required to enter/change the attributes associated with the entity being edited. This view is provided by the com.cohga.client.panel.edit view and so also needs to be added to the client configuration.

The most basic edit configuration interrogates the underlying spatial tables for the information it requires. (e.g. to determine what attributes are associated with the entity or what spatial geometries (point, line or polygon) the user is allowed to create)

The things that you can override are the parameters that the user can edit, the maximum number of geometry items the user can create, and the required number of geometry items the user must create.

Info

Parameters in edit configurations can be setup with or without a column attribute. If there is a column specified then the value will be written to the corresponding column in the underlying spatial table, if there is no column specified then no value will be written during this phase. However, the value the user enters for the parameter, in both cases, is available to be written as part of an audit configuration.
