Pass values between views of different window

[Former Member]

Hello Experts,

I am a newbie in ABAP Webdynpro. I have 2 views in 2 different windows. I want to pass values calculated from one view to the other view. But i cannot connect the views.

If the views were within the same window, I could connect them using inbound and oubound plugs with parameters. However in this case i am unable to establish the navigation link between these 2 views.

Has anyone of you experts come across such kind of requirement? If so, can you please guide how to connect the 2 views?

Thanks and regards,

Nitish.

Create attributes or nodes on component controller. Nodes and attributes will be 'globally' accessible.

Hi,

If you want to pass valse from 1 view to another views in different or same window,

create attribute in component controller for that vales . This component controller is accessible for views .

Hi shaira,

You are all correct. I had also this concept in mind.

The problem is that i want to populate the attribute of the component controller from a button click event.

I have only populate a node or attribute of component controller using the supply function. But here, its using an event of UI element.

Can you please indicate me how I can populate the attribute of the component controller apart from using supply function?

Hi,

The attributes of component controller can be updated any where as they are globally visible.....

if we have an attribute X type char1 @ component controller we can update it as

wd_comp_controller->x = '1'.

Thanks,

Hi ,

If you want to get the reference of the component controller in a button event use WD_COMP_CONTROLLER.

You can call the methods and attributes of the component controller by WD_COMP_CONTROLLER->

Hope this will solve your problem

Everyone,

I was finally able to connect the 2 views by using the component controller.

I created an attribute on the context of the component controller and read/set of the attribute of component controller on the button click event.

To access the attribute of the component controller, please find below a code snippet which was useful to me:

• Data declaration for accessing the component controller

DATA:

lo_component type REF TO if_wd_component,

lo_context type REF TO if_wd_context,

lo_controller type REF TO if_wd_controller,

lo_node type ref to if_wd_context_node,

lo_child type REF TO if_wd_context_node.

DATA lo_el_test_depts TYPE REF TO if_wd_context_element.

• get component controller API

lo_component = wd_comp_controller->wd_get_api( ).

lo_controller ?= lo_component.

• accessing the context of the component controller

CALL METHOD lo_controller->get_context

RECEIVING

context = lo_context.

• lo_context is the required context, from here we can manipulate its components

• get to the root node in context of component controller

lo_node = lo_context->root_node.

using lo_node i was able to read and write to the attribute i created in component controller.

Thank you all for your help.

Nitish.

HI Nitu ,

You can make a attribute in component controller and then store the data into it .

Since component controller is a global controller so any of your view can access this data .

As per your scanrio , store the data from the first view into attribute in component controller

and you can use this attribute value in your second view .

Windows have plugs too. Create plugs in the windows. Use the window controller inside the view to fire the window plug .
