Read ‘What it takes to reuse a view’ before reading this chapter.
Go to the component ->run time repository
and create a component usage.
Click on edit button and right click on
component usage and choose the option add component usage.
In the next dialog box, give name to the
component usage and details of interface view and component that we want to
reuse.
Choose continue once you enter the details.
Now this interface view will act as view in our own component.
Add this view to the overview page.
Save the runtime repository. Go to the
configuration tab of overview page and add the new view to displayed assignment
block section.
Now we need to take care of data. In the
previous chapter, we know that there is one context node BTPARTNERSET of
component controller of component BTPARTNER. So we will create one new same
context node at component controller level in our own component.
Go to the component controller and create
one context node with base entity BTPartnerSet.
Give the base entity name and complete the wizard.
We have created the context node. Then we
need to give the data to this context node. There are no of ways doing it.
Let us do it through coding.
As we know, in the event handler (will
trigger whey user clicks on hyper link) of result view, we got the BTAdminh
entity. We will fetch related BTPARTNER SET from it and feed it to the context
node of component controller.
Do the following changes in the event
handler. Save and activate it.
(This is just part of changed code
regarding above scenario. Previous code remains as it as ). once we got the header entity BTAdminh, we got
its related entity BTPARTNERSET using the relation. Once we got the required
record we added it to the collection and this collection is fed to the context
node of component controller.
Data feeding to context node is done. There
is one more important binding left between the context node of our component controller
to the context node of BTPARTNER component controller. As discussed we will use
the method WD USAGE INITIALIZE to do
this job.
Go to the component controller and redefine
above mentioned method.
Once you redefine, and then double click on
that method to open it. write the following code in it and activate it.
Sharing data across context nodes of
different components is done.
Test the application. If service contract
has any partners, then data will be displayed in the partner assignment block.
