Hi All,
The webdynpro component can be have mutliple views in it. And the views will have the n number of methods accordingly.
My question is "Is there any way to access the method of the view in a badi ( outside the webdynpro ) ?
For ex : Webdynpro comp : "POWL_TABLE_COMP" has the view 'REFRESH_CONTENT' and this view has the method 'ONACTIONON_REFRESH_CLICKED'
Is it possible to access this method in a badi ??
Kindly share your ideas please!!!
Thanks,
Pradeep.
Hi Pradeep,
1. the complicated way:
To trigger the action ONACTIONON_REFRESH_CLICKED of your view, you have to do following:
you can implement an interface-method (within componentcontroller) for your component (which embeds your view). This interface method throws event Refresh_View which again is being handled within your view. This eventhandler finally calls ONACTIONON_REFRESH_CLICKED.
So theoretically you can call the interface-method from anywhere. But you need the reference to your "living" component-instance. Here is the problem. How do you know when calling the BADI at application layer, which instance is alive and which instance to call?
I would try this: Create a static class which which manages a list of references to the living components with methods add_instance(..), remove_instance(..) and get_instances(). Methods add_instance and remove_instance are called in webdynpro when creating and destroying your component.
The BADI then calles the interface-method of all references within the static-class (which it gets by calling get_instances()), when executed.
2. the easy way:
If you just want to refresh your view, you should consider to add UiElement TimmedTrigger, which just executes ONACTIONON_REFRESH_CLICKED after a certain amount of time (every 10 minutes). It is way more difficult to realize a refresh when needed (BADI has been called) from application layer with no connection to webdynpro.
PS: Way 1 is just an idea, I've never tried it, but maybe it works. Maybe a guru can tell us if this works or is a bad idea.
