Login Action

---

The purpose of Login Action is to authenticate a user at the server. A Login Action is created automatically when you enable Security in your application. Login Action makes a request to the server where the authentication process takes place, based on the selected Security Provider. On successful login, the user is redirected to the Landing page configured against the user role.

You can edit the Properties, Data and Events of the Login Action from the Actions dialog.

Properties

Property	Description
Behavior
Use default success handler	If checked, on successful login, the logged in user will be redirected to the Landing Page configured against the user role (refer to Login Configuration under Security for more info). If a custom logic is required, uncheck this property and implement the logic under the onSuccess event of the Action.
Update data on input change	If checked, the component will be triggered automatically on the change of input data (as mentioned in the data tab) for the Action.
Request data on page load	If checked, 'Page' scoped will be triggered on page load while 'Application' scoped will be triggered on application load.
In Flight Behavior	This property determines the behavior when a call is fired through the action with the previous call still pending. Action queues all these calls, waits for the previous call completion and then based on the value of the inFlightBehavior property, decides what to do with all the queued calls: - doNotExecute - all the queued calls will be discarded, - executeAll - all the calls will be triggered one by one, or - executeLast - only the last call is triggered and the rest are discarded, this is the default behavior
Spinner
Spinner Context	This property specifies on which UI widget the spinner should show. Leave empty if no spinner required.
Spinner Message	The message to be displayed below the spinner. Leave empty if no message is required below the spinner. Note: If multiple actions are fired then the spinner messages will be displayed as a list below a single spinner.

Data

Data	Description
Input Fields
