DATA Transfer Between the VIEWS Using Data Modeler (Context Mapping)

DATA Transfer Between the VIEWS Using Data Modeler (Context Mapping)

Steps for Data Transfer between two Views:
_______________________________________________________________



Creating Webdynpro Project and Component, view and window.

-open NWDS in Webdynpro perspective
-select File-->New--->Webdynpro Project Ma
-provide Webdynpro Project Name
-Goto Webdynpro Components
-Right Click on Webdynpro Components-->create Webdynpro Component
-provide Component Name:
-provide package Name:
-provide Window Name:
-provide View Name: View1
-Finish


Editing View Layout, creating Attributes and simple form in View.


-Goto View1Context-->Create two Attributes( ID, NAME )
-Goto View1Layout-->Select Form Context ,Then Drag & Drop entire Context
-Save it.



-Now Right Click on Window & open "Navigation Modeler"
-Drag & drop Embed New View ( View2 )


create an OUTBOUND Plug on View1

-Create an INBOUND Plug on View2

-Create a Navigation Link between OutBoundPlug and InBoundPlug.

-Now Goto View1 and Drag & Drop a Button(NEXT) and create an Action by specifying an outBoundplug
-Finish.

For Detailed explanation on this go to my previous Video
"Navigation Between Views In WD JAVA Application" search for it in Youtube.



-Goto View2Context-->Create two Attributes( ID2, NAME2 )
-Goto View2Layout-->Select Form Context ,Then Drag & Drop entire Context
-Save it.


-Goto "ComponentControllerContext"-->Create two Attributes( IDc, NAMEc )
-Save it.


For Data Transfer : we need to Perform "CONTEXT MAPPING":


-Right Click on Component--->open DATA Modeller.

-Create a DataLink between View1 and Component Controller and perform "CONTEXT MAPPING"
-Create a DataLink between View2 and Component Controller and perform "CONTEXT MAPPING"




To Test the Component:
-Right Click on Applications:
-Create an Application
-provide Application Name:
-Finish:



-Right Click on Application & Deploy to J2EE Server.

This is how we transfer data between 2 views using data modeler and context mapping.

also


To access attributes of Component Controller:


wdThis.wdGet<Component_Controller>().wdGetContext().currentContextElement().get<Attribute>().

wdThis.wdGet<Component_Controller>().wdGetContext().currentContextElement().set<Attribute>().
