Hi,

If you are doing context mapping of the Reuable component's Node to some node in your component, then you just have to invalidate your node and the mapping will take care of the rest.

If you are not using Context mapping, you can call an interface method of the re usable component that can invalidate the context node.

Hi,

Thanks for your quick response.

Sachdev provide sample code which you have explained.

I was not maintaining any context in second component. just invoke method of component_1  from second component action method .I have created context node in first component. I want that context node reference in second component.How to get that context node reference in component_2

Hi,

Component 1 is the reusbale component. Component 1 has a context Node. If you want the reference of this node in Component 2, then:

1. Mark the context node in Component 1 as Interface node. ( You will see a checkbox in the component 1's context node properties )

2. After step 1, When you create the usage of Component 1 in the Component Controller of Component 2, you will be able to see the Context Node.

3. Just drag and drop the node from Right to left i.e. context of Component 1 to Context of Component 2 in the component controller of Component 2.

You wil get the reference of the node.

Thank u

i got the idea how to get the reference of component1 context node in component2

when we create the node must maintain the interface node property yes as well as input element(ext) property : yes

This is nothing but external context mapping

No.

This is not External Context Mapping.

Extenal Context Mapping would be if,

1. In Component 2, You go to InterfaceControllerUsage.

2. In the InterfaceControllerUsage, Go to the usage created for Component 1

3. Now map Context of Component 2 to 1.

But what we are doing above is mapping context of component 1 to 2.

Hence External COntext Mapping would be the reverse mapping of what we did above.
