Hi experts
I have a problem with passing a collection from one component UI to another usage component (Which is embeded ). Here is step.
1. I have created Z componentUI name "A" and add standard component UI (SRQM_INCIDENT_H) as a component usage to component A.
2. In standard component (SRQM_INCIDENT_H). I have created enhancement set "ZH_XXX" and start enhancing "SRQM_INCIDENT_H/MainWindow" by adding customize inbound plug called "ip_from_search_so".
3. Then I create Z component B. Create context node MYNODE in component controller and view controller , bind it together.
4. I have add Z component B to standard component UI (SRQM_INCIDENT_H with enhancement set) as a usage component. Enhance "SRQM_INCIDENT_H/IncidentVO" by adding MainWindow of component B (B_usage_name.B/MainWindow) in view area.
5. I go to configuration tab of SRQM_INCIDENT_H/IncidentVO . Drag the B_usage_name.B/MainWindow from left to right with load option "direct" .
6. In inbound I have just created "ip_from_search_so" . I have inserted snipped of this code below.
----------------------------------------------------------------------------------------------------
data lr_usage type ref to cl_bsp_wd_component_usage.
data lr_context_node type ref to ZL_ZCMPUI_S_BSPWDCOMPONEN_CN01.
lr_usage ?= me->comp_controller->get_component_usage( 'B_usage_name' ).
lr_context_node ?= lr_usage->get_context_node( 'MYNODE' ).
* building collection which is passed from inbound plug. (iv_collection)
..
..
..
lr_context_node->collection_wrapper->set_collection( lr_col ).
* END OF METHOD
----------------------------------------------------------------------------------------------------
7. Come back to component A. Create navigation link from A/mainWindow to SRQM_INCIDENT_H/MainWindow (ip_from_search_so).
Then I navigate from A to SRQM_INCIDENT_H like this route.
A-----------> SRQM_INCIDENT_H/MainWindow --------embed--------> B
After finish all these steps. I think the data in iv_collection should be passed to the context node of component controller of component B(in step number 6).
But it's not 
There are no any message. No any errors. Just display with blank context node (As it show data not bound)
Any suggestion ?
Thanks is advance
