Two ways to call it: pass a frontend event as val (e.g. cs_event-set_title) with its arguments in t_arg and the framework builds the event call; or pass a raw JavaScript expression as val (without t_arg) to run it as-is. The control/binding calls are frontend events too; their t_arg is positional (an empty argument between filled ones keeps its slot as ``): cs_event-control_by_id - call a method on a control resolved by id: t_arg = id, method, params. Any public control method works unless it is on the frontend denylist (methods that would break framework invariants). The named per-aggregation mutators are on the allowed side of that line - addItem, removeItem, removeAllItems, destroyContent - and only the GENERIC reflection variants that take the member name as an argument are denied (addAggregation, removeAllAggregation, setAssociation, ...). The view is passed as the separate view parameter (default cs_view-main resolves the id across all open views; pass cs_view-popup/popover/... to scope the lookup to that view). Two entries are NOT UI5 methods but frontend capabilities in method form: `css` sets ONE whitelisted CSS declaration on the control's own DOM node (t_arg = id, `css`, property, value) - for a value the control has no property for at all, e.g. the width of a sap.m.Page; prefer a bound property wherever one exists. `toggleBy` opens/closes a popup anchored to a control (t_arg = id, `toggleBy`, anchor id). An association setter (setSelectedSection, setSelectedItem) clears the association when its argument is EMPTY. Wherever an argument takes a CONTROL ID, it also takes an aggregation ITEM, addressed positionally as `//` (`carousel/pages/2`, 0-based). A control cloned from an aggregation template has no id the backend can spell - UI5 mints it from the template id, the parent id and the index, and the parent id carries the view prefix assigned at runtime - so this is the only way to reach one. It is the equivalent of the UI5 controller idiom `oCarousel.setActivePage( oCarousel.getPages()[ i ] )`. A plain id (no slashes) resolves exactly as before. cs_event-control_global - call a whitelisted method on a global object (MESSAGE_TOAST, MESSAGE_BOX, BUSY_INDICATOR, THEMING, POPUP, INVISIBLE_MESSAGE, FORMATTING): t_arg = object, method, params. POPUP-setWithinArea confines every popup to the control whose id is passed (sap.ui.core.Popup.setWithinArea, needs UI5 >= 1.89) instead of to the window; an EMPTY argument releases the restriction again. INVISIBLE_MESSAGE-announce reads a text out to a screen reader without rendering it (sap.ui.core.InvisibleMessage, needs UI5 >= 1.78): t_arg = text, mode (Polite, default, or Assertive). It is a singleton, so there is no control id - this is the only way to announce a change the backend made. FORMATTING-setCustomCurrencies registers currency codes the standard sap.ui.model.type.Currency does not know, or overrides their digit count (sap.ui.core.Formatting, needs UI5 >= 1.120): t_arg = JSON object, e.g. {\"BGN4\":{\"digits\":4}}. It REPLACES the whole registration - addCustomCurrency ADDS a single code to it instead (t_arg = code, JSON object). Reaching for the wrong one is silent: an app that registers currencies as it loads more data and calls setCustomCurrencies drops what it registered before, and the symptom is a wrong digit count in a table, never an error. cs_event-smart_variant_init - run the initialise( ) handshake sap.ui.comp variant management needs (a controller would call oSmartVariantManagement.initialise( fnCallback, oPersonalizableControl )). Without it the control keeps no personalizable control, saving a view fails inside sap.ui.fl and stored variants are never loaded: t_arg = SmartVariantManagement id, personalizable control id (optional, default: the first control that registered itself). The action waits for that registration, which the smart controls do once their OData metadata has loaded. cs_event-filter_bar_variant_init - wire a classic sap.ui.comp.filterbar.FilterBar to a SmartVariantManagement: t_arg = SmartVariantManagement id, FilterBar id. A SmartFilterBar knows its own fields and registers itself (see smart_variant_init above); a classic FilterBar does not, so a list report normally hand-writes the same controller boilerplate - registerFetchData / registerApplyData / registerGetFiltersWithValues, addPersonalizableControl( ) with a PersonalizableInfo, and a change handler per filter field that marks the variant as modified. This action does all of it, so saving, selecting and restoring a variant works without a single line of JavaScript. The restored values reach the backend through the binding of the filter fields, no extra roundtrip needed. cs_event-keyboard_shortcut - bind a key combination to a named backend event, the declarative equivalent of a sap.ui.core.CommandExecution shortcut: t_arg = combination, event name. The combination is spelled like the UI5 one (`Ctrl+S`, `Ctrl+Shift+D`, `F2`; ctrl/shift/alt/meta in any order, cmd/command/option/control accepted as aliases). Pressing it fires the event exactly like a button press and suppresses the browser's own default for the combination. Registering the same combination again rebinds it; an empty event name removes it. The registrations belong to the running app and are dropped when another app takes over. An optional THIRD t_arg SCOPES the shortcut: the scoped registration wins while its scope is OPEN and the unscoped one applies otherwise, which is how a UI5 CommandExecution in a Popover's dependents shadows the page-level one for the same command. A scope is either a view slot (cs_view-popover/popup/nested/nested2/main) or the ID OF A CONTROL that can be open or closed - a Popover/Dialog declared in the view and opened with control_by_id openBy, which never enters a framework slot. A control scope beats a slot scope (it is the more specific statement), then the innermost open slot wins. An empty event name removes the registration of THAT scope only. cs_event-binding_call - apply a declarative filter/sorter to an aggregation binding, the client-side equivalent of the UI5 controller pattern getBinding('items').filter(...); the model data stays untouched: t_arg = id, aggregation, method, params. method `filter`: params = path, operator, value1, value2 (empty values clear the filter); method `sort`: params = path, descending, group (abap_bool as `X`/``). Each of these events also works roundtrip-free when WIRED IN THE VIEW: write the same call where its result is consumed (`)->a( n = `press` v = client->follow_up_action( val = ... t_arg = ... ) )`) and the action runs in the browser without a server call. That is what the obsolete _event_client( ) did, and the only thing it did." ], "parameters": [ { "name": "val", "type": "string" }, { "name": "view", "type": "clike", "default": "cs_view-main" }, {
