The CALLSERVERONTRIGGER component is an invisible component, which calls a server side function (attribute ACTIONLISTENER) when being triggered. The function is executed after some duration (attribute DURATION).
Example use case: after having executed some server side function you want to clear certain information (e.g. messages) from the screen after 3 seconds.

General attributes are
Used inside: BEANPROCESSING
Binding to server side method that processes the events coming from this component.
| #{methodBinding} | Method binding |
Special binding to component adapter object instance on server side. The component adapter must be an instance of IComponentAdapterBinding. For some components (e.g. FIXGRID) there is an extended interface (e.g. IFIXGRIDComponentAdapterBinding).
| #{tobedefined} | Binding to IComponentAdapter instance |
Name of macro that is used for generating certain attributes of this component. Please pay attention: the value of this attribute is read one time for each control and cannot be changed afterwards.
Comment that can be asigned to any component. The comment is not operationally used.
| Any text | Any text |
Configuration information that is attached to this component. This information is not functionally used by CaptainCasa, but may be used for any application specific purpose.
Duration in milliseconds after which a request to the client is triggered. In case of TIMER components this is the actual polling duration (every xxx milliseconds), in case of LONGPOLLING components this is the duration after which the new polling request is sent to the server (in order to avoid, that there are too many requests).
| 0 | Deactivated |
| 1000 | 1000 milliseconds |
| 2000 | 2000 milliseconds |
Reference to an outside object that is the content behind the component. E.g. a field is representing a certain field of a database table: in this case you could define the value table;column. The reference plays a siginficant role within the attributemacro management.
| ref | One reference |
| ref1;ref2 | Two references |
| ref1;ref2;ref3 | Three references |
Flag that indicated if this component is rendered at all. If set to false then the component is not rendered - there is no component data sent to the client.
| true | Component is rendered (default) |
| false | Component is not rendered |
Trigger value: if the value changes then the component's activity is executed on client side. Use class Trigger on server side for implementations of this property.
