Event handling in zranges custom tag

[Former Member]

Hi,

I am using the tutorials by Thomas Jung on the ranges. I am faces a very strange problem. I have created that extension. My application framework is like bsp_model application. I have one main controller and two sub controller. when ever I chose any option,

An event is generated and do_Handle_event of main controller is called but ideally the do_handle_event of right controller should be called .Any Explanation about this behavior.

regards

Hello,

the event handler of the main controller is always called. You have to dispatch the event to get to the sub-controllers.

Please check TUTORIAL_3_MVC BSP application. You have to call dispatch_input( ). in the DO_REQUEST methof of your main controller.

I was just about to post the same thing as Dezso Pap. If you test this out and there is some other problem - with the tutorial perhaps - please post back here. I will have a watch on this thread just in case.

Hi Dezso,

> <i>the event handler of the main controller is always called</i>

As far as I know the Do_Handle_Event is called only for the controller in which event has been triggered it may be any sub-controllor or main controllor.

You are right that we dispatch the event through calling method Dispatch_input( ) in the Do_Request( ) method of main controller. Dispatch_Input do the followings...

1. First it calls Do_Handle_Data of sub-controllor's in the same order as they are instansiated in the main controllor and then finally Do_Handle_Data of main controllor is called.

2. Now Do_Handle_Event is called only for the controllor where event is triggered.

3 Now Do_Finish_Input is called in same sequence as Do_Handle_Data .

Correct me if I am wrong somewhare till now.

Now let me explaine my problem in detail...

I am using custom tag zranges in a view which is registered to a sub-controllor, I want to trap the event triggered when any option is selected but I am unable to do that. Please suggest me some solution to this prblem.

Thanks and Regards,

Hello,

maybe I was not clear enough, I meant the DO_REQUEST method of the main controller ist the one wich is always called. As here should the event / data be dispatched. /* Dispatch_input( ) */. Your steps are correct.

What event do you see gets called? /* debug */ Can the dispatch input find your sub controller? Are you using underscores '_' in BSP compoenent ID's? - it can cause problems (SAP note: #619450)
