Hi,

Component1 to component2 coomunication with in the project will be done through interface controller

1. First u have to Create One Application . That Application having One Component Controller.

2. And Create One more Component Controller in Same Application. Now you have two CC in Same Application.

3. Go to 2nd Component . have create any Values Nodes in under Interface Controller. Now u have to Mapping to the Interface Controller to CC

CC to View Controller.

In IC U have to Put Value Node cardinality 1..1 and go to Property is element = true( by default it is False, if u r not change this property the entire pracise will not effet)

True means ready to receive the data from the Child Node.

4. Comp1-àUsed Webdynpro Components-àAdd Used Comp(CC2Usage)Here name:This is 2nd Component Interface Controller name

5. Go to Comp1--à Used WebDynpro Components-àCompTwoUsage-àInterface Controller-àICComp1-àRight Click Edit

6. Here do mapping 1st CC to 2nd Interface Control
