Custom fields

Add a system settings panel with a custom fields panel to manage fields:

go.modules.community.addressbook.SystemSettingsPanel = Ext.extend(Ext.Panel, {
             iconCls: 'ic-contacts',
             autoScroll: true,
             initComponent: function () {
                     this.title = t("Address book");

                     this.items = [new go.modules.core.customfields.SystemSettingsPanel({
                                     // The entity it's for
                                     entity: "Contact",

                                     //Optionally override this function to customize the fieldset dialog.
                                     createFieldSetDialog : function() {
                                             return new go.modules.community.addressbook.CustomFieldSetDialog();
                                     }
                     })];


                     go.modules.community.addressbook.SystemSettingsPanel.superclass.initComponent.call(this);
             }
     });

Add the fields to the grid store definitions:

.concat(go.modules.core.customfields.CustomFields.getFieldDefinitions("Contact"))

this.store = new go.data.Store({
                fields: [
                        'id',
                        'name',
                        {name: 'createdAt', type: 'date'},
                        {name: 'modifiedAt', type: 'date'},
                        {name: 'creator', type: go.data.types.User, key: 'createdBy'},
                        {name: 'modifier', type: go.data.types.User, key: 'modifiedBy'},
                        {name: 'star', type: go.data.types.ContactStar, key: function(r) {return r.id + "-" + go.User.id}},
                        'permissionLevel',
                        'photoBlobId',
                        "isOrganization",
                        "organizations"
                ].concat(go.modules.core.customfields.CustomFields.getFieldDefinitions("Contact")),
                sortInfo :{field: "name", direction: "ASC"},
                entityStore: go.Stores.get("Contact")
        });

Add the custom grid columns to the column model with:

.concat(go.modules.core.customfields.CustomFields.getColumns("Contact"))
