Event from external window

[joerg_arndt]

Hi Friends,

I have a webdynpro component A. From there I open an external window including webdynpro component B.

Now, when I close the external window, I want to trigger an event in the calling component A, to update the data there.

By now I included the Componennts to each other, created an event in component B and creted an event handler in component A.

Now I open the external window B, from component A.

But when I press a button in the window with component B  nothing is happen in component A.

Do I need the Instance of component A to trigger this event and how can I get this?

The Problem is the external window , is there a solution?

Thanks in advance.

Hello,

Once you open an "external" window that opens a different browser window, you are in a completely different session (area in memory). You can't really communicate between the two sessions. If you need two windows to communicate, you just open a regular window which will show as a modal pop-up screen. Then, you can communicate back to the original window when you close the pop-up window.
