Or there is another way of invalidating context nodes.

If you are using Sap Potal 7.3 / 7.4 with AJAX configuration, try with standard configuration.

What do you mean by "rest button"? If you just want a button, place the button UI element on the screen and attach an action to it. This will trigger a server side event and you can refresh whatever you want in the screen.

Hello,

in the Reset button , what i have to write the logic. so that after pressing on the reset button during execution the whole application will be get refreshed. so that no need to press F5 again.

If you want to complete re-load the application, then fire an Exit Plug with the URL of the current application.

You should ask if you really need to reload the page, however. This is often the easy way out when you should really write your initialization logic in such a way that you can re-call it from within the application and reset the application state to initial without having to navigate back to the application via the browser.

I did suggest an approach - the Exit Plug.

Hi,

I will suggest that just write a method in which how your initial screen should look...And you can use a method called invalidate.

This method invalidates all elements of the node. This means that all elements and subnode instances are deleted. Afterwards the status of the node is as it is in its initial state. When an element or an attribute is requested again, the supply method is called, if it is available.

eg code:LO_ND_REGISTER->INVALIDATE( ).
