SDK 2.4 Native UI Builder : <view> event handler "uib,view,create" never gets triggered on view creation

I m building a Native app using SDK 2.4 Ui Builder.

I want to do some operations on creation of a view (like, check some condition once the view is created. Enable/disable few objects depends on the check).
I created an event handler for <view> on events "uib,view,create" using UI Builder.
But this handler is never getting triggered on <view> creation.

Any help would be appretiated..

I've tested the same scenario in my Windows 7 64bit machine using a tizen_2.4_Rev6 release. And it works without any errors.

Please check the generated codes.

1. Check the event handler binding code in {project}/src/managed/src/view/uib_view1_view.c file.

Please check the binding code in "uib_view_view1_create" function.
For example, evas_object_smart_callback_add(vc->root_container, "uib,view,create", (Evas_Smart_Cb)view1_onuib_view_create, vc);

2. Check the event handler code in {project}/src/event_handler/uib_view1_event_handler.c file.

void view1_onuib_view_create(uib_view1_view_context *vc, Evas_Object *obj, void *event_info) {
    // You can add your code here
    elm_object_text_set(vc->button1, "Hello....");
}

Please let us know the result and your developing environment information.

Thank you.

I m working on Linux Environment:

Details:

Ububtu 12.04 LTS (32-bit)
Tizen IDE: Version- 2.4.0_Rev5
               : Build- 20151223-1453

- Even handler binding code is NOT generated in {project}/src/managed/src/view/uib_view1_view.c file
evas_object_smart_callback_add(vc->root_container, "uib,view,create", (Evas_Smart_Cb)view1_onuib_view_create, vc); is also not present in my code.

- Event handler code is avaialble @  {project}/src/event_handler/uib_view1_event_handler.c

I  m getting "Unhandled event loop exception" when I add "uib,view,create" event from "Properties" window.
Hence its not creating the event handler binding code..
Error Message:
Unhandled event loop exception

Thank  you for providing your information.

According to your reply, I guess code generation process doesn't work properly.(- Even handler binding code is NOT generated in {project}/src/managed/src/view/uib_view1_view.c file)

Please post log file ({your_workapce}\.metadata\.log) after saving the layout.xml.

Hello Mr. Anoop CK,

We've found a bug which occurs when adding an event handler to the View that contains UI component that has an event handler already.

We'll patch this bug as soon as possible.

Sorry for your inconvenience.
