Communicate with two DCs thanks to Events

[Joseph_BERTHE]

Hi everybody,

So My question is about the events between two Development Components. I can't communicate to both DC !

I followed each steps of the tutorial <i>Using Server-Side Eventing in Web Dynpro Components</i> but something is missing because it doesn't work.

This technique work well inside my component (I can fire plenty of events without problems).

After debugging, I saw my program going into the interface and then fire the event. But nothing catch it.

Do you have any idea ?

Thanks.

You said: <b>I saw my program going into the interface and then fire the event. But nothing catch it</b>

Have you created a event handler for the event in the interface controller ?

Hi,

Thanks for replying.

So I have an event handler into my custome controler from my DC2.

Hi,

Then subscribe that event handler to the event in the interface controller.

Hello berthe,

Have you solved your problem?

Other options:

1. Create a Main component that use DC1 and DC2 as used components.

2. Use portal eventing if DC1 and DC2 are in different iViews.

Look How to use portal eventing withing a WD application in https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60d7d690-0201-0010-e581-9c4fc69c...

Good Luck!

Hi,

I didn't solve my problem. There is something weird in the behavior of my application. Because when I make the event process all worked well. And the next day it does not work anymore

I tried to do it again with two new DC and it work well. I'm getting crazy with WebDynpro !!!!

About your solution, my customer do not have the portal so I can't use the iViews Event.

Thanks anyway

Hi berthe,

Are you still using 2 individual DC or a MainDC using DC1 and DC2? perhaps with a MainDC you don't have that probblem.

As you said, something is going wrong in the behavior.

With a Main component you keep sure DC1 and DC2 are "alive" in execution time and both are in the same "execution context".

I don't know but just for try.... Has anyone another idea about what is happening?

Hello,

So I fixed my problem using the PlugIn/Out Event. This work because to communicate with my root component, I have one main view which contain View Interfaces. So I pass through the plug out /in to communicate (to change views).

Thanks all for your help.
