Sharing data across components in wdp ABAP

[Former Member]

Hi,

In our application, we need data to be shared across two components. For this, I am setting the context in the interface controller of comp-1, and trying to read it in comp-2. Comp 2 is a used component in comp 1, but this method doesnt work. I also tried using an interface method get_context but the references to the interface controller are different in both components.

Can anyone help me to go about this. Thank you.

Regards,

Nithya

Hi Nithya,

in oder to access a component-controller context-node 'A' of comp-1 in comp-2 do the following:

1. Mark 'A' as interface in comp-1

2. Declare usage of comp-1 in comp-2 and define used component comp-1 in component-controller of comp-2

3. Copy and map 'A' in component-controller of comp-2

4. Create component comp-1 in wddoinit() of component-controller of comp-2

5. access of 'A' data through wd_context->get_child_node('A')

Hope that helps.
